Firefox Support Forum

Hello. I just closed by accident my main window so I restored it, but it apparently lost all the container data and restored all non-pinned tabs to the default container.

Is it normal, is it a bug or is it a yet-to-be feature?

It feels like a bug because pinned tabs (which were not present/open in the secondary window that stayed open when I accidentally closed the main one) where duly opened in their respective containers.

When I try to go the the site https://tvlistings.zap2it.com/ it show top part of page while it tries to retrieve TV listings, but then the whole page goes blank. It still goes blank when in troubleshooting mode.

Works with Microsoft Edge browser. Any ideas?

I broke an old computer and have my logins from it on a backup drive in logins.json and key4.db. I can't work out how to transfer these logins to my new computer. I've tried creating a new firefox profile since I am nervous of losing logins that are on my new computer, but then I am totally lost.

Hello, Few days ago I noticed that Firefox started complaining about self-signed certificate issues, although I added my CA certificate to authorities months ago. It worked without any problem, but now I'm unable to open any of my internal sites anymore.

I tried to open a random site in Chrome, but the same issue. So you immediately will say the is in the certificate, but wait. I have few VMs running on Virtualbox, so I decided to test in there. Guess what, no issues at all. I tried in Fedora 25 (the Firefox version is below 100), then tried Windows 100. Both worked. Then I decided to update FF to the latest version, guess what - it broke again =]]

So something has changed, but I really don't have a clue what causes the issue. I attach the screenshot of detailed CA view from Firefox.

Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

I went to settings and set firefox to open links in a NEW TAB instead of a new window, but it still opens links in a new window. I did a search on google and when I click on the link for the website to see the information it is still opening in a new window. How can I fix this so I don't have a lot of new windows. It's irritating to have to close all those stinking windows just to get back to my original window. I just want the links I click on to open in a new tab.

hey folks,

since today firefox wont load any websites out of troubleshoot mode. not even settings/ about:config. if i open a page in a new tab it just stays blank and nothing is happening.

in troubleshoot mode i turned off hardware acceleration - nothing changed after restart. i updated the runtime file "Visual Studio 2015, 2017, 2019, and 2022", which is suggested in different help-posts, i deactivated all addons, i created a new profile and also tried an imported one from eralier today - so far nothing has worked.

i also reinstalled firefox with version 99/ version 101 two times, after i cleared %APPDATA%-data.

im also just using windows defender as antivir.

please elp, i'm out of ideas.

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

Firefox version: 101.0 (64 bit) OS: Fedora 36

I have an extension (completely blank) that can't be deinstalled. I am trying to use the "refresh firefox feature" to get rid of it, but the button simply isn't where it should be. The text is german, but none if these Buttons are the one I seek.

Why are google sites (Youtube, Gmail and Search) getting disconnected when all other sites are still connected to the Net? This has been happening since November 2021.

When that happens I close the FF and then immediately open it. Now the google sites work properly.

Never had that problem with other sites.....never!

Why the hell is this happening? Is FF responsible or Google?

So what is the solution?

Been using Firefox for long time on a Win10 machine. Motherboard failed. Saved the C drive. Question is how to move bookmarks (profile files ?) from the old C drive to the new Win11 computer? I tried moving the profiles over from the old C drive to the new computer but Firefox would not recognize them and shutdown. Restored the Win11 files and Firefox is again happy.

This question has to do with logging into web sites with an email and a password. Firefox 101.0.1 (64-bit). Windows 10.

On many sites, when I click in the email field, a drop down list of email addresses appears from which I can make a selection using the mouse or up/down arrow keys. Some web sites have as few as two email addresses in the drop down list, others have many more. I recall that one site has about fifteen email addresses in the drop down list.

How can I remove a non-applicable email address from the drop down list?

How can I clear the drop down list of all email addresses?

Thanks.

Hi, I have this problem that is driving me crazy, I know it is not an issue with firefox but I really appreciate any help.

The problem is that there is a grey html code in inspector when rendering the html page, the grey code is not exist in my original file but that grey code I had already deleted it after using it a while, but it is still appears as grey code in inspector and this made me some issues in jquery.

So how can i get rid of it ?

Thanks

I used a siteblocker and i tried blocking about:addons, wouldn't allow it so someone tell me how. im literally trying to prevent myself from removing extension i literally jumped from one browser to another just to make this shit possible please.

Lighter fonts (from multiple families, and on multiple websites) are rendered so poorly they are barely legible.

I already tried disabled performance settings, and turning off ClearType in Windows (it barely had any effect)

How do we fix this?

I've been using Firefox almost exclusively for years now, and it's always worked flawlessly - until recently! Now, when I log into my GitHub account, I can no longer edit and commit my changes.

When I click on the "pencil" on a rendered page, I am taken to the "edit page" where I can make my changes (in markdown), preview those changes (rendered in markdown), and then commit those changes. Beginning very recently (within the past few days), the preview tab is no longer functional, and I can no longer commit my changes to the file.

I've verified that GitHub has not changed their interface by logging in from my Chrome browser, and following the exact same procedure used in Firefox everything works as it always has.

I recently upgraded from ver 99 to 100, and now to 101.0.1. I recall clicking a pop-up immediately after the 99-100 upgrade that had something to do with cookies... sorry, I know that's lame, but it's all I can recall now. In any case, I am certain this happened recently.

Please help... I have to use Chrome for a couple of things already (my brokerage account at Vanguard for example), but I despise Google, and want to limit their spying.

Thanks,
