Hello everybody,

There are more and more websites that have functions that no longer work with Firefox and force me to use Chromium instead. Do you if there is any chance that an upcoming release will put everything right?

I have reinstalled the OS on my lap top and after a successful login to my account I am unable to sync everything from the account. The logs can be found in: https://controlc.com/8afabe84

I have the same account set on two different devices (My desktop PC and my android phone, this device I am trying to sync is the third one) and both those device were synced long time ago.

I tried with another profile which I am using for my work related stuff, still no success. First I tried syncing on Ubuntu 20.10 and then installed on Ubuntu 20.04(currently) but it is without success.

I need to sync to this device the bookmarks, extensions, saved logins, etc... Currently I do not have my other PC to export this stuff, please help.

Some of the thing in the logs:

## FF profile choice problem on Linux Mint with Claws email

I have three FF profiles on my Linux Mint 19.3 system (work, not-work and one for e-tail). Somehow the problem only appeared after I added that last one. All profiles have the same syntax; I checked the files. Neither one is set to be the dominant one. Typically, I don't use more than one at a time.

I also use Claws mail. Whenever I get any mail with a link I want to check out, I just used to click on that link and it opened in a new tab in the FF browser profile that was currently open. Similarly, whenever I wanted to see the HTML version of a mail, I right-clicked on the html-icon and chose open. Again, it picked the open browser.

Now, though, whenever I pick either one of those options above, I get the "Choose User Profile" box. If I pick the profile that is currently open, I get an error telling me that it's already running.

Since I mostly read email when I use the no-work FF profile, I tried to add "firefox -P NotWork -no-remote --class NotWorkProfile" but that also resulted in the choose user profile box to open.

My current work-around is to copy the link and open it in a new tab, or pull the whole mail into the tab to see the HTML version. Quite annoying.

Is there any way to get it to ignore all other profiles but the currently open one? Thank you for anyone who has an idea. Let me know if there's anything else I may add to explain the situation.

[My apologies if this isn't the right forum; I'm also attempting to ask this question in the Linux Mint and Claws forums, if those exist.]

Recently, I had to change my username at my bank's website because somebody was trying a brute force attack on my password. Now, the site still shows my old username, although I've gone to my Saved Logons in Preference and removed all logons for that site except for the correct one. I have to delete the old username from the typing box every time I log in there, after which I can select the correct (and only) saved username/password.

Hi,

searching for bookmarks (with sidebar) is no problem. There are several cases where I look, if something or similar had been bookmarked already. With this I want to avoid doubling/tripling/'moreling' bookmarks. But if I find something already bookmarked, I do not know in my about 1000 bookmarks where the bookmark is located. I tried to show properties of the found bookmark but it does not tell where it is placed. So I would have to look manually about 100 folders to find where the bookmark is located.

The most easy solution I think, would be indicating the place of the bookmark when showing settings of bookmark. On hovering over the found bookmark in a third line of popup could be told the location of this bookmark and would be visually more pleasant I think.

Else I have to put the bookmark doubled in a more visible location and delete the bookmark found by search. This workaround works but is not intuitive and bothersome (and costs much more time).

As this solution would be easy to implement, I hope, this can be implemented 'soon'. I think, this would help many others, too. (At least I heard from several others in my environment, that they miss such a thing.)

Not forgetting, thanks for the great browser, Niels

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

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.

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?

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.

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.
