Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Many site issues can be caused by corrupt cookies or cache.

Starting in safe mode didn't change anything! As I said I tried to delete cache/cookies didn't help! I tried all time, it logged me out...

Remove History For One Site {web link}

Open the History Manager <Control> (Mac=<Command>) <Shift> H. In the search bar, enter the name of the site. Right-click on one of the listings and select Forget About This Site. This should remove all information, including any site settings

It doesn't even find that site, or even when I use part of a link, as it is crazy long! That is the thing! As it is google tab. I have bunch of google tabs, which are locked with captcha and I can't see what were in them before to reopen them...

I called for more help.

So???

Not likely anything from this. I tried to start it in safe mode and clear cookies+cache (everything) - didn't help.

I tried now to sync clock and javascript should be on. I don't know how anything else could affect captcha like e.g. zoom levels...

What do you mean by "old tabs"? If you want to use a page which contains captcha, perhaps it should be loaded anew; i.e. bookmark the page and don't use an "old tab".

That is the thing: I had opened tabs of google.com where I searched for something, I wasn't done with that! And now these are permanently locked with captcha. I can't access that information anymore!

What happens if you do a new search?

As said I don't rememeber what I searched for! It is not apparent from URL! Also read Firefox suffers from this problem lately. So it is probably not last time it will happen!

Bump.

Hello hello, does anyone exists, or I Am only person in the existence? My tabs are still locked by captcha BTW...

This issue can be caused by corrupted cookies or blocked cookies.

• check the permissions for the domain in the currently selected tab in "Tools -> Page Info -> Permissions"

If clearing cookies didn't help then it is possible that the cookies.sqlite file in the Firefox profile folder that stores the cookies got corrupted.

• rename/remove cookies.sqlite (cookies.sqlite.old) and when present delete cookies.sqlite-shm and cookies.sqlite-wal in the Firefox profile folder with Firefox closed in case cookies.sqlite got corrupted.

I already deleted cookies.

This didn't work either! Now captcha doesn't even show lol. I think don't care anymore LOL. Just hope it won't happen again...
