a similar problem in a browser installed with apt (but when running in safe mode, there is no problem, and manually disabling extensions and cleaning / refreshing firefox, does not help). When installing via snap, there is no such thing, but it does not suit me for work, since there is a problem with profiles.

I would be very grateful for your help in solving this problem.

Details: Имя Firefox Версия 87.0 ID сборки 20210318103112 ID дистрибутива canonical User Agent Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0 ОС Linux 5.8.0-48-generic #54~20.04.1-Ubuntu SMP Sat Mar 20 13:40:25 UTC 2021

Firefox can't load any page, including about:config and about:preferences. about:support is working. All menus and surrounding UI is working too, but, for example, if I try to open Preferences page from menu - it will not open, even new tab isn't created.

If I start firefox with MOZ_DISABLE_CONTENT_SANDBOX=1 all works fine. Problem appeared after I accidentally used all of my laptop RAM with other app. Firefox didn't crashed, but after reopening this issue is began appearing.

I use Linux Mint 20, and apt-upgraded all packages (including firefox) right after this issue first appeared. I tried to: - restart browser (didn't work) - restart laptop (didn't work) - use different profile (didn't work) - use browser safe mode (didn't work) - clear caches (didn't work) - disable all extensions (didn't work) - use different versions: 75.0, 87.0, 82.0, freshly-compiled by myself (didn't work) - refreshing firefox (didn't work) - run firefox with MOZ_DISABLE_CONTENT_SANDBOX=1 (worked, but it's obviously unsafe and don't fix the root problem)

I found some issues and bugs that looks pretty similar to mine: https://support.mozilla.org/en-US/questions/1245935 https://support.mozilla.org/en-US/questions/1235332 https://support.mozilla.org/en-US/questions/1279656 https://bugzilla.mozilla.org/show_bug.cgi?id=1433065

Also, after closing firefox, it stays running in processes, and I can't open new window for 30 seconds or more after closing old window.

I think it's bug and problem is somewhere in firefox sources. Do you have any ideas, how can I fix this?

Sir/Ma'am,

Is the version of Firefox in the Linux repositories the China version with an American facelift?

I know you all do not have command and control of this, but I thought someone should be aware that the default Firefox browser for Linux installs seems to be the CCP Firefox and not American version. With all the CISA activity, it might be something to look into.

I here refer to my thread https://support.mozilla.org/en-US/questions/1285212 in which the problem were not even answered by any of your tech people, but archived - why?

I find it really bad, if i post a bug and you just archive without even try to fix the problem! It makes me extremely angry! Bad behavior!

Please stop that and re-open the case.

Jan Ps. same system (Lenovo Thinkpad X300 with Xubuntu 16.04LTS 64bit (account A) )now running Firefox 85.0.1 64bit can now print, I can't find any mentioning in release notes to how previous version 75.0 and now this one is different and why this one now can print.

It would be nice to get this solved, since other people here has had this one too and it seems to jump between versions and OS(linux an windows).

Hallo,

My previous thread was archived, but further regression has occurred so I'll bring it up here again as feature requests are down. I'm still using 56 one reason being that there are separate control options for the start page and the home page. I like to start with a blank page, but have the home button available for my #1 destination. The current version of firefox combines start and home pages, thus taking away my options to separate these elements. For a while it wasn't in the GUI, but you could fix it in the about:config (which was my previous "solution"), but with the latest updates this has been removed as well.

How do I get separate start and home pages? If I could assign a value to the home icon that didn't affect the start page, that would work too.

         Tak!

My computer was updated with the latest linux and the latest firefox browser. I want to create folders in my bookmarks. All the help answers say to go to Bookmarks and click on 'Menu'. That does not come up as an option. All I get is: Show all bookmarks; bookmark this page; bookmarks toolbar; other bookmarks. I can't find anything similar in tools, edit, or file. I also don't get 'Edit Bookmarks' like was in the last edition I had.

Firefox fails to use some local fonts

After installing the Native MathML extension (to get MathML typeset equations on the Wikipedia, as suggested on mediawiki.org), all equations set by MathJax/MathML turned to using STIX instead of Latin Modern. I'd like them to stick to Latin Modern instead.

The only possibly related setting I've found is font.name-list.serif.x-math in about:config, whose value is Latin Modern Math, STIX Two Math, […]. I tried to manually change the font family specification of some text to see if Firefox could use Latin Modern Math to begin with, but apparently it can't (see first screenshot attached), while it loads STIX allright (second screenshot). Latin Modern is not the first locally installed typeface I haven't been able to use, but it's the first one I have really tried to (I don't remember which one the other typeface was).

My Latin Modern font comes from TeX Live 2019 installed using the TUG installer, not Fedora's package manager. fc-list | grep -i "latin modern math" returns /usr/local/texlive/2019/texmf-dist/fonts/opentype/public/lm-math/latinmodern-math.otf: Latin Modern Math:style=Regular. I'm running Firefox 87 on Fedora 33.

When I go to https://www.sz-shop.de/ostern, FF tells me that there is a risk

"Warnung: Mögliches Sicherheitsrisiko erkannt ... Am wahrscheinlichsten wird das Problem durch die Website verursacht und Sie können nichts dagegen tun. Sie können den Website-Administrator über das Problem benachrichtigen."

That is what I did. I called that shop and told about that warning. The lady on the phone also went to the address, but she did NOT see that warning. She confirmed that her PC was OUTSIDE of sz-shop.de like mine.

So the problem is a potentially wrong warning? Or how can we explain that I see a warning and other people do not see it?

Hi guys i'm new in the forum so i have no idea if anybody else allready had my problem,i've tried to fix it myself but i cant seem to get it done. Yesterday i had a problem with my OS linux,and i had to reinstall the system,while i was pretty sure i had all bookmarks saved in an external HD i went straight to a quick format and reinstall of the OS,after installed all the due system update.

The Problem:

While i was importing the bookmarks.html i stored in external HD i noticed that nothing was being added in the bookmarks of Firefox,so i tried few times just in case i was doing something wrong but still nothing was being added in the bookmarks,so i tried to import the bookmarks on Tor Browser and the same thing happened nothing was imported. So it came to my mind that the .html file could've been damaged. Now i tried many ways to open the file either in command line or text editor i even tried using libreoffice,in the case of text editor,command line such gedit,pico,nano it loaded the file but it was heavily encrypted,in the case of libreoffice shortly after i tried to open the file popped up a message telling me that the file was corrupted and libreoffice couldn't read it and stopped.

I need a solution to either fix the .html file or decrypt it so i can recover the web addresses inside and it would be very bad for me since my bookmarks.html is 3.3Mb large with ALOT of bookmarks inside.

Can anybody tell me how to?

Thank you in advance for any help or suggestion that may help me to retrieve my bookmarks. Ludo.

P.S. OS Linux BackBox 7 up to date along with it latest version of Firefox that update server provides me.

Hello dear community,

I recently switched to a dual boot system and got Ubuntu 20.04.1. If I want to watch Netflix for example I cannot because of DRM settings (at least the pop-up of Firefox says so). Other video and audio content is working fine so far. The guidelines on what to do to solve the problem like this

We have a new add-on of our own that we were trying to add to the Firefox browser. This add-on was tested locally and worked fine. However, upon trying to install the official add-on to the browser, it is throwing the following error, "Installation aborted because the add-on appears to be corrupt".

Any suggestions to address this issue would be appreciated.

I also noticed another post or two about the same topic. As per those posts, the issue got resolved automatically after some time. Can I expect the same?
