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.

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.

While browsing https://www.mathrubhumi.com/ site, a warning will come "A webpage is slowing down your browser, what would do like to do, stop it or wait" Then system monitor shows a web content is consuming around 4.5 GB and firefox itself stopped the webpage. If the memory usage is higher the system will hang.

As the subject stated, I'm desiring to achieve the result that I can run some webpage with the window containing only the page itself (without toolbar, address bar, etc.). The --kiosk command line option is almost what I need but it will enter the fullscreen mode whatsoever. For instance, chromium has the --app option which is exactly what I want it to be. Thanks in advance!

Hi! I am trying to move FF profile with saved data such as extensions (anti-captha). Tried just copy a profile folder but not successful. It is not contains folder "extensions". Please help!

The firefox extensions expect to find the respective javascript files inside their definition folder containing manifest files and related resources Is it possible to access and share the same user library (js file) between all extensions without having to copy it back to all the extension folders when it is modified? Thanks for any suggestions you have

Hallo,

I have two firefox profiles with which I wish to share bookmarks. An easy solution is to create a symbolic link replacing the one places.sqlite file with a link to the file in the other profile, thus we're always just using one set of bookmarks and all is happy. However, Firefox keeps overriding my link; labeling the file "corrupt" and replacing it with a cached version. I need to know how to stop firefox from overriding my input and respect the changes made in the profile folder. I need to disable whatever mechanism is going on that is checking the files and reconstituting them.

                                Tak!

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!

I have a Monitor + Laptop Setup and whenever I open Bookmarks from Bookmark Toolbar it's opens on the second display (Laptop) and not in the primary display (Monitor).

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).

Sir/Ma'am,

My system is a standard install, and when I open Firefox, click Help, About Firefox, and then click the linked word (Mozilla) "Firefox is designed by Mozilla" it takes me to "www firefox com cn" ?

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.

Kernel: 5.4.0-70-generic x86_64 GCC v: 9.3.0 Desktop: Cinnamon 4.6.7 Distro: Linux Mint 20 Ulyana Base: Ubuntu 20.04 focal

Firefox for Linux Mint: 87.0 (64-bit)

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?

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.

When I click the three dots in the address bar to open the page actions, I am not able to see any options it shows an empty box. It started happening recently. My version is 84.0.

Thanks in advance for helping out.

Ps. I have attached the screenshot of what exactly is happening.

Hi everyone,

Thanks a lot for taking time reading this! :)

I have the following problem with my firefox on Kubuntu 20.04 on my laptop: since a couple of weeks, firefox opens normaly after rebooting, remembered all tabs and my firefox account etc., but it's just not loading anything. I can still type in a web adress or something in the search, I can also still select the drop-down menu on the right ("Open menu") and select e.g. "Settings", but nothing happens afterwords. Same problem for all websites. Some of the main buttons are also not functional (refresh, back/forward). I attached a screenshot from the "empty" firefox (but not sure if that's of any help anyways ;) ).

I tested a couple of things so far, nothing helped:

1) Internet is working, I tested ping, apt is working as well as a differnt browser I installed now).

2) I reinstalled firefox completely by running the following commands:

      sudo apt update
      sudo apt purge firefox // sudo apt --purge autoremove firefox
      sudo rm -rf .mozilla
      reboot
      sudo apt update
      sudo apt install firefox

      (Since I removed the profile folder, the standard tab and bookmarks open/show after starting firefox now, as expeced. I'm also not longer logged in.)

3) By starting firefox via the console, no error messages were shown

4) I created a second ubuntu unser profile, to test if firefox would work there: it doesn't

5) Since I have a dualboot with Win10/Kubuntu 20.04, I started Windows and tested firefox there: it is working as usual.

6) I also obviously tried to google this problem, but either I put the wrong keywords in or this problem is pretty unique/new?

If you need any further information on my system, I'm happy to provide them! Thanks a lot for any recommendations and further ideas, what to do! I'm pretty much desperate for a solution by now, as during home office a not well working system is a pain! ;)

Thanks and stay safe, Katrin
