Firefox Community Forum

Hi there! It started yesterday. I keep getting warning messages from Bitdefender that a connection Firefox was trying to establish was blocked. I will include a screenshot of the warning. I searched the link included in the warning and it comes up as a Firefox related link. I had six or seven of these warnings within the last 3 hours of using the computer and am concerned and irritated. Firefox is updated automatically on this computer and I think the last major change would have been the "cookie jar" thing(?). Obviously, the warning only says that the a certificate has expired. Thank you in advance for your help. Yours sincerely,R.

Hey guys,

I kinda need your help. I just switched from Windows to Manjaro Linux and I cannot retrieve my Firefox bookmarks and passwords. I do not have access to the old setup because I have formatted the disk and I have only this one on Linux.

I have used my Firefox account multiple times in order to login on a new device and every time it has retrieved my bookmarks and passwords but not this time. Before logging in from this device I had to reset my Firefox password because I had forgot it -- is this a security measure maybe?

Are my bookmarks and passwords gone forever? Thanks!

I've been seeing this more and more, but my toolbar will change by itself every restart. The add tab button will shift all the way to the left or not appear, the bookmarks won't appear, etc. I'm not sure what can be causing this, and I saw no way to "save" my current configuration other than pressing the done button upon using the custom toolbar, which I had done every time prior to fix my configuration. Does anybody know why this is occurring, and a possible fix? Thank you

On 2015 MBP Mac OS El Capitan 11.6 new Firefox 78.15.0 esr won't sync with my older MBP running El Capitan 11.6 but it will sync to the 2015. How do I get the 2015 replacement computer to sync?

When I open Firefox browser it automatically opens 3 tabs at web sites I have chosen . Now I want Firefox browser to automatically open a 4 th website. It was easy to do this several years ago by clicking on the opened website and moving the address to the home button. But this doesn't seem to work now. Has the process changed or have I just forgotten how to do it?

My profile seems to be corrupted. Starting Firefox with that profile completely crashes the computer, but when I reinstalled Firefox and it started with another profile it was fine. Switching back to my profile immediately crashed the computer. Is there a way to extract the history/bookmarks/passwords/etc. from my profile folder without starting Firefox? Thanks in advance!

This if Firefox 131.0 on MacOS 10.15.7 (Catalina).

Firefox 131.0(aarch64) OSX 15.0.1

1st Issue: The 'Clear Cache' doesn't seem to completely clear the cache. Eg: I'm logged into gmail, I go to Privacy & Security and then click Clear Cache and History. I navigate back to gmail. I'm still logged in.

2nd Issue: When I right click and 'Open Link in New Private Window' this doesn't actually take me to a private window. I have to select File/New Private Window and paste the link to that window.

Suddenly this morning, a new toolbar appeared on my copy of Firefox (131.0) showing one item, Getting Started, which I have no use for. I managed to delete it and it was replaced with something telling me to place my bookmarks here on the bookmarks toolbar, which I also don't want. How do I get rid of it as it's nothing else for me but a waste of screen real estate?

I accidentally clicked on "never remember passwords" and now Firefox doesn't ask me if I want it to remember a password. How do I reverse that so that Firefox does ask me if I want to remember the password?

Hello,

There has been an upgrade of Firefox ESR to version 128.3 on Debian 12 bookworm.

Before the update, I could play videos, now I can't.

I precise I can play videos on Chromium, or with the video players.

I have libavcodec58, libavcodec-extra59, ffmpeg 5.1.6 packages installed.

There is an error in the console: Media resource xxx.webm could not be decoded. Specified “type” attribute of “video/mp4” is not supported. Load of media resource xxx.mp4 failed.

This command seems to indicate the session is X11 and not Wayland: ``` loginctl show-session 1 -p Type Type=x11 ```

I am getting the following error message: Platform version 131.0.1 not compatible with miniversion. Please see the screenshot attached for further details. I cannot open firefox due to this error message and I receive this error message every time I try to open the Firefox.

Dear Mozilla expert,

Firefox consumes a lot of memory resources for inactive tables. in other browsers there's a feature to disable processing of inactive tables does Mozilla have such feature in their roadmap? if so, then when it can be expected?

I use Firefox on Ubuntu Linux, and it works fine.

For unrelated reasons I have created a new Linux Mint 22 boot partition, and I would like to use the same Firefox profile on both Linux OS-s, without having to move or copy the existing profile I use on Ubuntu. (The profile is placed on a third independent data partition!) I cannot find any information on how to do it. All information I find involves moving the profile, but then Firefox on Ubuntu would not be able to continue to use it.

I look forward to hear from you. Thank you. :-)

The answer from here doesn't work anymore: https://support.mozilla.org/questions/1394194

So is there any updated answer for the current version of Firefox? Else I will have to downgrade and disable updates for the future. This new version is making it impossible to drag the browser around when it's below a certain width, because it covers the tabs area 100% now. I really need the feature to drag my browser around without maximizing it every time.
