Win10 with what was Firefox 89. I had already disabled the Proton UI on this installation, because it is horrible. Today Firefox decided to update to version 91. All of the Proton UI junk is back. I tried disabling it again, but nothing worked. Doing a web search, it appears that Mozilla has disabled the ability to turn off Proton.

I then set about to rollback the installation back to version 89. I found a Mozilla link on this, went to their ftp server and downloaded the installation files for the last version of 89. The installation went normally, but when I opened Firefox afterwards, a little box popped up saying something to the effect of "To keep your History and Bookmarks from possibly being corrupted, Firefox must create new user profile." I exited out of this and Firefox didn't start. I attempted to restart Firefox again and the same box popped up again. The only way to get past it was to click the accept button.

I did so and Firefox started. This was clearly not version 89. As the UI is junk, it took several minutes to find out that this was now the latest version of 92!!!! I'm absolutely positive that I downloaded the correct file. When I look through the update history, it doesn't even show todays version 89 installation as happening. What a piece of junk.

I then spent 20 minutes figuring out how to revert back to my user profile, not the new one that it had created for me. I then did some research on what had happened. Well it turns out that you can't actually rollback Firefox, despite what Mozilla says. For a while they have added "downgrade protection" which automatically creates the new user profile and stops your old profile from being accessed by it. So unless you want to figure out how to spend a hundred hours reconstructing bookmarks, passwords, settings, etc. it actually isn't possible to rollback Firefox. Doesn't this violate some Microsoft rules about being able to uninstall versions of software from within Windows? If you try to do this with Firefox and go back to a previous version it blows everything up.

Does anyone know how to actually rollback Firefox to a previous version, so that Proton can be disabled?

Hi, there are certain extensions which will not pin to the toolbar, including (for example) google translate. I have tried refreshing, clearing the cache, deleting and reloading, all to no avail.

ROLLBACK THE LAST UPDATE THAT ERASED THE MP3 DOWNLOAD BUTTON THAT I PAID FOR BECAUSE NOW IT IS GONE...THAT IS A RIP-OFF....I SHOULD GO TO RIP-OFF REPORT DOT COM AND REPORT THIS...I CANNOT BELIEVE THAT I PAID FOR AN ADDON AND FIREFOX KEEPS PUSHING AND PUSHING TO DOWNLOAD UPDATES TO THE BROWSER AND FOR WHAT?! FOR MY PAID SUBSCRIPTION TO DISAPPEAR? THIS IS AN OUTRAGE!! TALK ABOUT THE ICING ON THE INFLATION CAKE!!

I just updated my Firefox Developer edition and it completely deleted every add on and customization I had on my browser. Same for Firefox for iOS.

I have an "Old Firefox Data" folder on my desktop but I have no real way to make it work with the newly downloaded and overwritten new browser.

Am I the only person who's really sad about this?

Also, on the iOS browser I'm no longer able to create a BLANK PAGE as a start page for BOTH HOME AND NEW TAB.

How do I create that? There's no option in the dropdown on the mobile settings. And it does not allow me to type in about:blank and then select in the mobile settings. It just stays red and then disappears when I try to do it again.

Why did you rearrange the furniture so HARD?????

Thank you, Still reinstalling all my add ons after 2 days, Jean

During my work i often need to have massive amount of tabs, and want to switch between them quickly. And i cant find solution to tab size change, aside of "workarounds" that are "planned to be shit down". Is there a way to do it on permanent basis? I don`t mind those tabs be wide as they are now (although prefer them to be smaller, about 6x times) if i can, for example, have second and third string of tabs. That should be sufficient. But still i cant find a way to do so. I also saw mention of "user feedback" in another thread (currently locked) and would be willing to participate in said feedback.

# My problem

When i go to some site with video (for example https://www.openproject.org/ ) i have the following message : "To play video, you may need to install the required video codecs".

# Spec

I run Firefox Beta in Fedora, it's installed in /opt/ folder. I have the "normal" version of firefox too and the video works well.

# Some other infos

The video seem to be a mp4 video and i have the following package installed in my fedora GStreamer Multimedia Codecs (Multimedia plauback for APE, AVI, DV, FLAC, FLX, Flash, MKV, MP4, Speex, VP8, VP9 and WAV).

Hi, I've been having issues with Firefox for some time now. Every page I got to throws a NS_ERROR_NET_INADEQUATE_SECURITY error. I cannot fix it by setting network.http.spdy.enabled.http2 to false is because Firefox then starts crashing. In the past I've gone around the error by turning http2 off, but recently, first the developer edition, then after today's update to 91.0-0.1 of stable version Firefox crashes if I turn the feature off.

The developer Edition started throwing NS_ERROR_NET_INADEQUATE_SECURITY sometime in spring, then started crashing in June I think. The stable version followed soon as described above.

I am submitting this ticket from a beta version, which for some reason does not have this issue.

I thought it may be the Linux version of Eset, but removing it did not help. I cannot think of any other reason why am I getting those errors, but it seems I am alone because my colleagues don't seem to have this issue neither on macOS, nor Windows.

Hello, I have a strange problem, so after loading the system, the processor in my computer is drastically loaded, after entering the task manager, it turns out that one firefox process uses a lot of processor (photo in the attachment) after closing this process everything returns to normal and CPU consumption even while browsing the internet does not exceed 7% but it is quite persistent because I have to close this process every time, I will just add that this problem does not occur in other browsers. and none of my friends have it either. I'm using Windows 10 with the latest updates and the latest Firefox developer edition. The problem has been around for about a year and is really bothersome. My processor up to i7 2760qm, I have 16gb of ram. I will also add that in my second laptop with core 2 duo, this also happens only with me, no one who has this problem. Thank you in advance for your help.

On firefox all sounds coming via laptop speaker only, cant use bluetooth headsets. Tried couple of things, connect bluetooth before starting firefox or connect bluetooth after firefox starts. Results same, any audio coming only via laptop speaker. I can use bluetooth headsets on other browser or audio/video player.

I also have firefox devloper edition, it also behave same.

Hello, Since my last update, Firefox 93, my bookmarks present a huge line spacing between them, line spacing that I would like to control to see more bookmarks at a time. Do you know how to proceed ? Thank you very much.

In Chrome, the browser allows you to monitor all events fired on the window by typing "monitorEvents(window)" in the console. Firefox has no such function (that I can find). Can someone tell me how to do the same thing in the Firefox console? Otherwise, what is the JS event that gets fired when zooming text only on the browser? Normal zoom fires the resize event, but when text is zoomed it isn't as straightforward. I know that I could alternatively check the font size on the element, but that is not an event. Thanks!

How can I permanently force firefox's automatic updates to be turned off? Which guy modified the original design for the new version of Firefox bookmarks? Is there something wrong with that man's brain? Is the spacing of the new bookmark item too large to read? It's very uncomfortable.

FFox 92 update today. Menu spacing went to double. No shock there. Found the CSS code below for UserChrome.css and set it up.

EX. menupopup > menuitem, menupopup > menu {

 padding-block: 4px !important;

}

root {

 --arrowpanel -menuitem -padding: 4px 8px !important;

}

Here's the issue: I want it tighter than 4px. So, I set it down to 2px... eventually dropping it to all 0px settings.

EX: menupopup > menuitem, menupopup > menu {

 padding-block: 0px !important;

}

root {

 --arrowpanel -menuitem -padding: 0px 0px !important;

}

But, it doesn't get any smaller than the above 4/8px set up. Bug? Perhaps there's another CSS setting to be tweaked for V 92? I do not have any other CSS for these items elsewhere in my UserChrome file.

Dark Mode used to work beautifully in Firefox. Today it stopped working. I can choose Dark Mode in the settings page, and the settings page itself then uses Dark Mode. But Dark Mode does not work in any of the other pages, only the settings page. I think it must be a flaw in an update that was installed automatically today. (September 7, 2021)

Is there a way to uninstall this update and go back to the previous version. Dark Mode used to work beautifully and Firefox was my favorite browser. Can someone help? Thanks.
