After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Firefox on my 2018 MacBook Pro started having issues downloading all file types after I disconnected Dropbox sync and backup. Each time I try to download a file, a failed message is displayed below the file name and type. The browser was using the downloads folder that was synced with Dropbox. After disconnecting Dropbox, I tried changing the downloads location, but the "Choose" button does not display a window. The result is the same whether the Always ask you where to save files is checked or not.

I have gone through the following steps trying to resolve this issue with no success.

1. I have reset/cleared any configuration setting found using about:config and browser.download.
2. I have launched Firefox in troubleshoot mode and tested downloads with no resolution.
3. I have uninstalled Firefox and installed a fresh copy from mozilla.org with no resolution.
4. I have set the downloads folder in Safari, but this did not provide a resolution. Downloads work as expected in Brave and Safari. The current downloads location is the Downloads directory on my iCloud Drive.

The second screenshot with the error attached in still referencing the Dropbox-connected Downloads folder. No other browsers are using this folder and the Dropbox app has been completely removed from my laptop.

I use Firefox for web development and need to be able to download various files throughout the day, so this has become very frustrating.

Any help is greatly appreciated.

Cheers,

Updated Firefox and all my bookmarks are gone. I tried to follow the directions but could not figure out how to get the bookmarks restored. Please help with simple instructions.

Thank you, Joe [email protected]

12/1/2024 - Hello, I have a Lenovo desktop computer with windows 10; & I was having a problem today getting into firefox, after they did an onscreen update, while I was on the computer this morning...I then installed it again by accident by hitting the 2 firefox apps that were located in the start menu (without uninstalling the previous version from 11/3/2024)...& then I noticed that none of the multiple bookmarks showed up...So then I contacted AOL remote support to help me uninstall both prior versions; & then reinstall firefox; & it still did not sync the bookmarks...So now I just tried again to sync the bookmarks through the Mozilla website & they still did not show up...Also I am now unable to browse with firefox...It only lets me do a google search, even though I selected the firefox app as the default web browser...Please advise me what to do...Thanks, Ron Bruno

Hello, since I installed the latest update of Firefox (133.0) two days ago I'm having trouble to load videos on some websites it's giving me a black screen when I try loading them so i'd like to know if anybody knows how I could fix this ? I tried clearing cookies, cache and resetting the browser and it still doesn't work.

I know this problem has been caused by the latest firefox update (133.0) because all my videos are loading fine on both Chrome and Explorer but i'd like to keep Firefox so if anyone has an idea how I could fix this it would be very appreciated thanks!

The first image speaks for itself. When I want to change the way this setting is set in a Facebook group, when Firefox is full screen, the associated dialog is so placed and/or sized on the screen that it is partially truncated on the left by the left side of the display. I just checked in MS Edge and it displays normally there with full screen display. It displays normally in Firefox when I Restore Down. So this one at least does seem to be specific to Firefox.

I have a second full screen display issue that may be related, but this one isn't just Firefox; Ms Edge also shows it, and other applications also behave similarly: the right hand scroll bar disappears in full screen (as does the applicaion menu control)! I had some trouble taking a pair of images to illustrate this, using Snipping Tool. The second image, when Firefox is set to restore Down, shows the scroll bar and application menu control, which is what I see. The third image was more tricky to take because the first time I tried, the screen capture included a scroll bar and application menu control even though they were not visible on screen. I had to redo it and be very careful not to let the right hand side of the selection drift off the right hand side of the display.

It seems like the full screen display is just a little "larger" than the physical display. I have tried one or two other screen resolution settings and that has not helped. My best guess is that it's a monitor settings problem, but I've also fiddled with the monitor settings, again with no success. And even if a monitor setting explains the pervasive right hand side issue, it doesn't explain the Facebook dialogue issue, which does appear to be Firefox-specific.

So my current workaround is just not to have anything full screen :(

I have been having this issue for a while now. I will get this message on different websites, and then if I try again later it might work. It seems like it's a random chance of me getting this error. I have tried "about:config" commands as suggested on other posts on this forum and they didn't work. I checked my licenses, proxy settings and still nothing. I got another web browser to see if it's my PC or Firefox, and the other browser worked just fine. I am guessing there is something I need to do within Firefox, but I am not sure what that is.

i restarted firefox, and on it's new tab when re-opening it offered the "review checker", so i clicked the "try on amazon" I don't get the icon in my search bar. is it an add-on/extension that i can just search for in the google store even though it's in beta?

since a few mins ago, 30/11/2024 12 Am IST i have observed that MSN webpage specifically : https://www.msn.com/en-in?ocid=wispr&pc=u477 auto opens every few mins, i have no idea why, can anyone help me?

My up to date FF screen starts shaking, primarily using Youtube for awhile and then going somewhere else. It will still start shaking using various websites. It takes a PC reboot to stop it. It does not happen using Chrome. I have done the following with no change: 1. Fresh install 2.Turned off hardware accel. 3. cache clear refresh 4. All extensions off 5. Started in Safe mode. This lasted the longest but it eventually started shaking.

Something to note: My screen size randomly increases/top tab bar disappears when typing something. It's random but it's new like the shaking.

YouTube only on Firefox has terrible stutter/frame pacing issues, most prevalent when watching 4k/60 content. "Stats for nerds" shows a healthy buffer and minimal dropped frames. This issue is not present when watching local videos or on Microsoft Edge. The issue can be alleviated by watching in 1080p60 but stutter/judder is still present. The issue is not resolved no matter what power or performance options I choose in my laptop's settings. Any help is super appreciated, as I really don't want to open Edge every time I need to use YouTube. Thanks!

Hi everyone,

Prior to the release of Firefox Desktop 133.0, which I believe came out today on 11/26, I was using the profile switcher that was in the Firefox application menu. I had all my profiles created in about:profiles and I had browser.profiles.enabled set to true. This allowed me to easily switch between profiles by pressing the hamburger button in the top right. However, it is no longer appears for me after the latest Firefox update. I'm not exactly sure if I'm missing something, or if this was intended as I know the profile switcher was a work in progress feature.

This reddit post shows what the feature looked like. I will also attach the images.

If anyone would know why this no longer appears to be working, or how to fix it I would greatly appreciate it. I know I can just use about:profiles or some other alternative, but I found this to be the most convenient.

It certainly appears they have, with the left and right padding growing wider. In fact, they both look about twice the size of the top and bottom padding, whereas before I remember them as being about equal. The change was immediately apparent with my home page!

Any particular reason for this?
