Firefox Support Forum

Hi folks,

I'd like to obtain some clarity on provenance aspects of Firefox released as a Flatpak.

I see in this article that one of the options is to use flatpak package: https://support.mozilla.org/en-US/kb/install-firefox-linux

Is this article produced / reviewed by mozilla? Is flatpak an officially trusted, backed by mozilla, means of installing firefox on a system?

On flathub one can observe the "Verified" seal which indicates that such package is developed and maintained by original package developers (in case Mozilla). One can also observe in multiple forums here and there that mozilla is the one that builds and maintain this package.

Though a seal is nice, and users opinions are ok, it would be good to have artifacts that would evidence better this relationship. Also, would be good to have this officially stated in mozilla's website, under "Download options and other languages" section, something like "you can also safely install firefox through the flatpak package available on flathub which is developed / maintained / signed by mozilla itself".

Or maybe all of this information is around and i am just not able to link it together.

Thanks

I'm using Ubuntu 24.04 and just reinstalled for unrelated reasons. I'm trying to copy my Firefox profile over from my backup to the new installation.

I used the Ubuntu Snap store to install Firefox and put my old profile in -- this is the one that I was using on my previous Ubuntu 24.04 installation just a couple days ago -- and everything seems fine, but I do see this error message:

[ERROR error_support::handling] suggest-unexpected: Error opening database: Incompatible database version: 18

It gets printed when I type things in the search bar, so it seems related to some sqlite database related to history and autocompletion.

Is there a way to fix this? I'm fine with just deleting it, so long as the other parts of the profile remain.

(This is a strange error, since after all I was using the exact same setup -- Firefox on Ubuntu 24.04, installed via snap -- just a couple days ago, and it was, as far as I know, up-to-date.)

Hi, in my settings Firefox is set to "remember history", but there are no options for how long and when i look into my history, it doesn't go back further than a year. I found a few answers to this on some forums talking about the places.history.expiration.max_pages setting and others about the places.history.expiration.transient_current_max_pages setting but those don't exist in my Firefox and the threads are more than a decade old. I currently have version 126.0.1 64bit on Linux. How can i keep my history forever?

I want to enable cookies for outlook only,the rest I don't want.

I have attempted to look at the cookie's url for outlook and add that to the exception list, but outlook still harasses me with its annoying 2fa

How do I find the actual address to put in the exceptions list to stop this issue?

here is the video: https://streamable.com/zffknq the issue is about transparent bar with vertical addons and slowly fullscreen animation, and the fullscreen animation isn't config-able, I already set full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 in about:config, and disable sidebar or userChrome is not work too. and this is happend about one mouth ago after my nixos update firefox.

For about 24hr now, every time I clear cookies and cache data, 20kB remain. I clear this data often, and the cookie and cache data always registers "0kB" after I click on "Clear Data", until yesterday. My OS is Ubuntu 22.04. Where can I find that file so I can delete it?

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?

heb.com i can login, but my password manager takes me to

accounts.heb.com, & it gives me the error message. I went to

heb.com, logged in & saved it. When I looked at passwords again it had

accounts.heb.com, & I cant edit that. I don't know if its Firefox or HEB.

FireFox assumes that text size is the same for all pages in a domain, rferl.org for example. That is _not_ true. If I have set size to 50% and then take a link to a page that's different and have to set size to 67% to read it, when I return to the original page, size is 67% and text is too large.

Hello Firefox community and thank you for your time and effort. Let me begin by saying I used to have this same issue with MS operating systems until I said goodbye to MS and went to Linux on one laptop and got a Mac for streaming and graphics. Here is the issue: MS had so many background processes running constantly, regardless of what I was using the machine for, that I regularly experienced crashes, warnings and slowed responses on my Windows machines. No matter how vigilant I was about settings and stopping processes and keeping system clean, I would regularly have to replace the fan on my machines as the constant overheating would eventually kill the fans. That has not been a problem since I made that switch away from MS. Until now. I keep clean machines and keep them updated religiously. But with the latest few Firefox updates the problem is now back on both my Linux built Lenovo and my MacBook Pro, especially the Mac. That regularly shuts down after an hour of streaming use. When I hear the fan constantly struggling and feel the machines heating up I check the background processes and find that Firefox has at least four running processes eating up resources. Force stop does not fix the resource hogging; by the time it is apparent and I respond the machine is already overheated and shuts itself down. Last night I started searching and found a (very) recent thread about this same issue. Most of the participants were attributing it to recent updates. If this is the case is there any effort to fix this? I would hate to have this issue completely destroy my older (but still heavily relied upon) MacBook with this constant mechanical challenge since I cannot afford to replace it. Please can you fix this problem. It is an old and exhausting struggle I thought I would not have to deal with again. If my assumption of the source of the problem is inaccurate do you have any suggestions? Thanks again, Jerri

Firefox losing all of my session history is an inevitability. I have encountered this problem on many cases over the past decade, be it due to an update, a power failure, a BSOD, or just randomly (despite closing the application correctly); like a law of nature, eventually firefox will just forget to open a window, or the entire session. This issue has caused me to switch to other web browsers in the past, multiple times. They each struggle with this in their own way.

Sometimes I can save my session by finding it in the sessionstore-backups folder, but the problem I am talking about is that that does not always work! Often times the backups get overwritten when the problem occurs - even if I don't touch firefox or open it again or close it, even if I immediately notice that a window that was there when I previously opened firefox is no longer there, often times nothing in the backup files actually has the version that I want. It's always overwritten with the new/modified session that's missing hundreds or thousands or tabs from my session restore history.

I think that the ability to actually restore a session and not have to cross my fingers that it doesnt blow up and delete my entire history (which randomly occurs at least once every few months) is the biggest problem with firefox. It is the most frustrating thing that any web browser can do. And quite frankly even if I wanted to use Firefox Sync to store my session information on a remote server (which I do not!) I do not actually trust that firefox will actually not fumble it and randomly delete my session every few months, given the history of how this problem has existed as long as I have been using this software. At least with the local sessions, sometimes I can recover some of the data, which isn't an option when firefox sync inevitably drops my session history. I am on the verge of setting up some kind of recurring task to back up the session store files on a regular basis just so I don't go crazy.

So: why does this problem exist? Is there a long running thread about why the session restore system sucks? Will it ever get fixed (even having multiple backups or the ability to manually save a backup in the UI would be a major improvement)? Are there community supported tools to fix this problem by saving extra copies of the sessionstore files?

Hi,

Yesterday I set up a new computer, installed Firefox and logged in to my Firefox account. Everything went well, my bookmarks appears, all (!) my extensions were installed, everything looked fine. Then I went about my way configuring unrelated Linux stuff, using Firefox as normal on both computers, no problems.

But at some point, I suddenly noticed that on both computers, the icons for most of my extensions had disappeared. And sure enough, looking in about:addons, all that was left were five addons (Dark Reader, Simple Translate, uBlock Origin, Dictionary Anywhere, OneTab). And on both computers, including my main laptop (!), where I hadn't done anything other than clicking around in websites.

And it only affected the extensions, my bookmarks, history, etc all is fine and synced between the computers.

No restarting of Firefox, choosing different profiles in about:profiles (there was only one other, a mostly empty one), nothing got them back. And looking in ~/.mozilla/firefox/, sure enough extensions.json and all extension related folders had been changed, looking as if I never had more than these five extensions installed.

And when I installed one of my usual extensions again, all of it's settings and customizations were back to default. So this is not just a case of having to reinstall a few extensions. All custom uBlock filters, all Tampermonkey scripts, etc, everything is gone.

I tried looking around on the web for solutions, but it appears that there is no one who has had this exact issue before, and I couldn't find any indication that there is any way to revert such an error by Firefox Sync.

To my luck, I have a secondary laptop where I should have a mostly up-to-date instance of my Firefox profile, from which I will now try to recover my extension data, but if that weren't the case, years of fine-tuned settings and customizations would be gone.

As people rely on Firefox Sync to back up their Firefox data, instead of backing up their Firefox data "against" Firefox Sync failing like this, I'd think this is not something that ever should be possible to happen. At the very least, there should be some way to revert errors like this. Perhaps Firefox Sync could store backups either server side or client side before syncing deletions like this?

Hello,

I have created a webpage with a canvas element that allows the user to draw an irregular path by pressing down the mouse, similar to the free drawing of a paint application. The issue is that the very first time that the user presses the mouse, the line stops abruptly, while the next times the lines are drawn correctly. The events seem to fire correctly and the page works fine at Chromium, so it seems to be a Firefox issue. You can find the html page below. I am curious, what could be the problem?

This has been a problem for a while, currently on Firefox 126.0 and Nvidia 550.78. I can work around the problem by forcing webrender to use software mode.

When using HW accelerated webrender with my Nvidia graphics card everything works fine until the PC wakes from sleep, then graphics are broken and Firefox needs restarting. Most noticeable for me is when looking at Grafana graphs they will look like random lines, and my Frigate NVR snapshots only display some of the time.

Is there anywhere in Firefox that will show a log of any error messages to do with the graphics card? I would like to try and fix the problem rather than disabling HW acceleration, but with no logs to look at that is impossible. No other programs seem to have a problem with resuming from sleep, and no error messages are shown in any of the system logs.

When I open Firefox and call up bing maps , it starts to load the page , then Firefox crashes . Has been doing this for several firefox versions . Looking at the crash report , I always get "The debug symbols are missing for firefox. Please install firefox-dbg." but I can't find firefox-dbg to load

https:\\archive.org works perfectly in Firefox on Win-10, but on a new Linux Mint install, (with default Firefox as included), this particular website simply displays as a blank white screen. Every other website I try on the Linux install works perfectly; it is only this one website which does not work.

There are no add-ons, no proxies, no security suites, nothing extra. I cleared all cookies and cache. Tried running FF in Protected Mode. Nothing seems to fix it.  There are no error messages displayed - just a blank white screen.

And, to make it worse, I am not particularly computer-literate, (I'm 82 years old...), so you will have to give me simple guidance if I need to get involved with deeper logging etc.

Somehow I cannot type an apostrophe, whenever I do it just shows whats between the brackets ( ).

What I do: 1. Press the apostrophe button 2. Press space

Expected result: '

Actual result:

I m on Firefox Linux and my keybord is set on INTL
