Firefox Support Forum

I am having trouble to open firefox browser for ubuntu 20.04(focal). I have also delete mozilla folder from cache and then reinstalled again. I have tried to rename profileini file. Finally I have uninstall and install using terminal by "sudo apt install firefox" but still I am getting this error "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

How to resolve this.

Thanks in advance.

After running `snap refresh firefox`, many sites I use no longer render any text.

Via some fiddling via the developer console, it appears to be that any text with `font-family: Helvetica`. Removing that CSS restores the text, adding it removes the text.

There's a fix for CVE-2023-29537 in this release that affects font initialization - possibly related?

Today when I closed Firefox and reopened it the option to restore previous session was not shown, as a result I have lost half my pinned tabs (I managed to redo the rest from bookmarks) which were vital. I tried going into history but the option was greyed out.

This happened yesterday too but after redoing half my tabs I went to open gmail and it restored all my tabs, I tried the sane today but it failed so am stuck with half my tabs.

Please do not suggest I use synch as I only use one device.

I installed Firefox-ESR on my Raspberry PI and noticed that I cannot play Udemy videos. After some research I found that the Widevine plugin is missing and the OpenH264 Video Codec is also not installed. Following the instructions from similar issues didn't solve the problem. I ticked off and on the "Play DRM-controlled content" button but this only brings the widevine plugin for a moment and after that it disappears. In the network tab I see no activity when click on this button, i.e. Firefox does not send requests.

Additionally the OpenH264 Video Codec is not installed and never installs.

Any ideas how to solve this?

I have a 'site' that is just files on my hard drive.

I need to click an anchor link such as: <a href="file:///dir1/dir2/dir3/dir4">Store Your Files Here</a> and have Firefox open the folder dir4 with the systems file manager. ( In my case the file manager is Nautilus ) ( Ubuntu 20.04 )

I have seen this: http://kb.mozillazine.org/Links_to_local_pages_do_not_work but it does not describe a scenario that uses the file:/// interface.

It also does not provide any information about how the files will be handled.

I can get the folder link to work currently , but it appears with the: 'Index of file///...' in a browser tab.

Obviously you can not use that for anything useful.

The main goal is to open the folder and be able to use the system file manager to include more content for the site without having to navigate to the folder manually. The folders I want to display are buried many levels down without the possibility of having descriptive names. I have ~121 pages/folders in this arrangement , and each one has content for each page. I would like to add a button on each of the 121 pages that will open each of the pages content folder.

Having this issue with Youtube since a few days ago, on version 115.0.2 and 115.0.3, and only for videos encoded in AVC/H264. VP9 and AV1 encoded videos have no trouble buffering, only H264 is affected. Happens with or without adblocker, and on different OS. Cookies cleared, no dice.

Video would load the first 20-40 seconds, then does not buffer at all subsequently once it reaches the end of that portion. I have to skip a few seconds forward for it to load the next 20-40 secs, then it would get stuck again.

I can get around this issue by either lowering resolution to 480p (which looks terribly unwatchable), or turn VP9 streams back on (which does not work correctly on my setup, there's a driver bug that hasn't been fixed).

The sure way, and strange thing, is that AVC/H264 videos load and buffer with absolutely no issue when I'm logged out of my account. Also, works with no issue in Chromium, even while logged in.

Anyone facing this or similar issue recently too? Is it still ongoing for you?

I cannot use firefox. About the third or fourth tab or window I open hangs up, and then all of firefox hangs up. The triggering load can be from bookmarks or a new site. Have rebooted, re-opened: same problem. Have updated everything (including snap), same problem. Uninstalled and re-installed Firefox, same problem. Troubleshooting crashes and will not re-start

Dear Support, I posted my js-library on the hosting https://rombase.ru/o5/olga5/o5.js and copied it to https://leonrom.github.io/o5/olga5/o5.js

I try to connect to it from Blogger, for example: https://olga-5.blogspot.com/2020/02/olga5-shp.html?o5debug=2 and I change the link to the library's hosting in the <head> of my blog.

The Chrome browser works the same way wherever o5.js is located. But Mozilla, when placed on rombase.ru, swears in the console: `The resource at “https://rombase.ru/o5/olga5/o5.js” was blocked by Safe Browsing`

My Firefox is 109.0.1 (64 bit) under MX Linux

Could you please tell me: what is the "safety"-difference between rombase.ru and leonrom.github.io? What shall I change in rombase.ru to work properly?

Thank you PS Connecting via VPN (from Ukraine) does not help

For several years now Firefox keeps the methodology to update in the background and then force the user to restart.

This always causes some loss.

There are multiple situations where this is not acceptable. Just to give one example: I just logged in an account and clicked to receive an authentication SMS. But then Firefox forced restart and I cannot login nor ask for a new SMS because the previous request was recent.

In my opinion this makes absolutely no sense. Is there an option the turn off this forced restart?

Beginning this evening, I can no longer log in to my online google account.

I keep getting asked for "Two-Step Verification", but this doesn't work: I give a 'phone number, but my phone never rings. I once received a "Google verification Code" of [removed], but that didn't work, either.

I DO NOT WANT "2-step verification"; I don't need any special login protection.

How do I eliminate 2-step verification? It starts with "Sign in to keep your new Google News and get news based on your interests. ... Sign In", but never allows me to sign in!

recent upgrade to 116 causes issue of fast timeouts, Reddit, Youtube will load for a few seconds then stop, refresh, restart don't help. Running in troubleshooting mode now so I can post. I'll narrow down which addon is at issue

Hi, I have firefox on my Ubuntu 23.04. When i start it it shows a black screen. I click quit on my system and then i startup and it lunches normally. What am I doing wrong or how to fix it?

Hello, the Firefox app often stops responding when I have multiple tabs open or when a more demanding process is running in a tab. Also, Firefox stops responding when I copy a screenshot. I have tried the browser without any extensions and the problem persists. I use EndeavourOS based on Arch linux, I use the current version of the system and Firefox.

Dear, I always have a lot of tabs opened and I guess I had one too many opened yesterday. Already I had to recover my settings after a crash the day before. So I had the crash and restarted the pc yesterday evening. All my tabs were gone, so I shut down the pc and started up again this morning and still no sign of restart or nothing of my tabs, history, all my Linux worksheets were completely empty accept for this page... I went to settings to restart the previous settings but it always does that automatically, and it only started the one I was in this morning (the empty one) I tried for a crash rapport but could not find one. How do I get everything back, please ?! I need to get the tabs back before this previous session! Please help... Where can I find them? What can I do? I can't have lost them all ... I will go nuts .. Please help me! My system is a Linux Mint 21.0 version, I think Thank you so much! Nadine

If I try to access https://bugs.cacert.org I get an error message: SSL_ERROR_EXPIRED_CERT_ALERT

If I access to the same site with chromium browser, there is no such error message, even more: I can access the certificate with the following information: valid until 2024 (see complete cert as picture).

Why this obviously wrong error message? How can it be circumvented (a warning might work, but a blockade?)?

I have many addons and some add a context menu with specific options. One that I often use is "Copy Plain text". Can it be moved upwards, can the order of the context menu list of options for addons be customized?
