Firefox コミュニティフォーラム

I just experienced the XPcom not loaded issue. Uninstalled Mozilla Firefox and re-installed. All of my logins and passwords are no longer available in programs I saved to the "Pocket." What can I do?

web page Northern Tool wont display. Get a page that says "Northern tool cant display in your country" Is a US company - I have an account there - get emails from them every week. This just started last month.

I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

Hello! I am a developer, and I am making my own adblock-based Firefox Extensionto block ads. And I have a problem, I use manifest 2, ads are blocked, but the changes are applied only after the Extension is restarted, which should not be the case. Maybe there are some specific settings that I have not found, because for example on Opera and Chrome the Extension works perfectly and the changes in the blocking rules are applied immediately without any application restarts.Thanks for your help

I tried to open Firefox and a message appeared: "Couldn't load XPCOM". I uninstalled the program with Revo Uninstaller Pro and downloaded the latest version. I selected Run as Administrator but there is a message that says "Windows cannot have access to the selected device, path or file. Maybe you don't have access rights". However, I do have access rights. I have checked it multiple times. How can I install Firefox and see it work properly? Thanks

I know I can hide the sidebar by clicking the button on the toolbar. But I'm used to opening my bookmarks and history with ctrl+b and ctrl+h, and being able to close them the same way. This still works to close the actual bookmarks/history, but the sidebar doesn't return to being hidden (despite being hidden before I opened them), it hangs around taking up space on the left of my screen. Even after I removed everything so it's just a useless blank rectangle with "customise sidebar" at the bottom, it defaults to staying open unless I click the button. It's really annoying. Is there any way to make it hide itself again automatically once I'm done using it?

I updated my desktop browser today and now there is an expandable sidebar at the left margin of the window showing tool icons for Tabs from other devices, History and Customize sidebar. I can see how to remove tool icons and how to expand or collapse sidebar but can I remove the sidebar completely? Is this an option? I prefer the old look with the browser web page content extending all the way to the left of the screen, without the narrow vertical sidebar.

I have a 1848ETC-HST data logger from Real Time Automation on an isolated network that does not support HTTPS but Firefox keeps changing it to HTTPS. I tried a private window with the same results. HTTPS-Only Mode is disabled. I entered an exception even though it should not need it. It was working in Firefox at one time and it still works with safari and chrome.

I have been using Firefox for my browser and have an account. Yesterday I clicked on the Firefox icon on my taskbar and it just opened with a blank screen. I need all of the information stored on my Firefox account. WHAT HAPPENED?? IT WILL NOT OPEN TO FIREFOX!!

Hi,

My laptop had broken and I had to reinstall Windows. All of my files had been lost on the C drive, including Firefox bookmarks. Sadly there weren't any backup json files anywhere else. Is there a way to recover those bookmarks somehow?

Thank you, János

Twice now in the past couple of months this has happened to me:

Restart to Keep Using Firefox

An update to Firefox started in the background. You’ll need to restart to finish the update.

Your windows and tabs will be quickly restored, but private ones will not.

EVEN THOUGH in my Firefox settings this is set to no automatic updates.

What is happening?? How do I turn this off! This seems like a virus? Please advise.

During the past week I have been receiving 408 Request Time-out errors on a subscription website our organization uses. The vendor reports no changes to the site and no other customer complaints. All searches I've done point to my local browser or network setup, but I've cleared cache and cookies and it's not my network; I'm currently on vacation and getting the same errors 3000 miles from my home. It has worked fine for the past six months until last week.

I'll have to stop using Firefox if this continues. Please suggest some ideas why this suddenly started occurring and how I might fix it.

Some of the firefox built-in search engines have several comma-separated associated shortcut keywords in Settings/Search/Search shortcuts, e. g.

• @duckduckgo, @ddg for DuckDuckGo

But if I type in several comma-separated shortcuts for any other search engine, none of them will work as expected in the address line. What is the correct way to assign several keywords for the same search engine, like it is already assigned for some default engines?

the following files couldn be attached outlook web Microsoft Outlook in firefox. Its files more 1 MByte. clearing the cache did not solve the problem. Outlook web in Microsoft Edge no problem with attach files Firefox version 133.0 (64-біт)

How do I remove the sidebar permanently. It is now as I said above about 2.5cm wide and growing! I want it gone and none of the solutions give any idea how to do this. The show/hide button only made the damn thing expand!
