As the title suggests, I just want firefox to be nice to use again. Since its latest update it is far from nice. Too much stuff is set to darkmode, even though I have googled like crazy and fiddled with most, if not all, about:config options to try and restore it.

I will do whatever it takes, but my firefox theme (abstract firefox) must remain intact. Surely there is something I can do in the userChrome.css or whatever it's called.

It is just so very tiring having to fix mistakes made by firefox, that keeps changing stuff for the worse. Changes that nobody ever asked for. I am giving the browser one more chance for old times sake, since I have been using it for 20 years or thereabouts. So please, firefox... stop trying to force your users into using stuff that your staff team or whatever likes to use. Think of your users.

And please help me out.

Thank you.

On a trusted website, for a class which I paid a lot of money to attend, I get this error message, on FireFox only: The media could not be loaded, format is not supported.

I used to LOVE Firefox,but I'm getting frigg'n irritated by it right now. Chrome and Safari both open this page. I had this same problem a few days ago, was sent a long list of possible ways to deal with it that were all over my head complicated. I chose the simplest one- to clear caches, and it worked! yay, for a couple of days, now the error is back. I there must be a different solution , or cause, than the cache one - What needs to be turned on or off, so this doesn't happen? Too complicated, too frustrating.

I'd love it if someone could give me some more ideas on this. Macbook Pro 16" 2021, IOS Monterey 12.1

Thank you!

Hello. First, fantastic work on the browser! Second, recently my secure connection to a specific site keeps dropping. I use Firefox to connect to tutanota.com (de). I have HTTPS Everywhere and uBlock Origin installed. Before recently, I never encountered this issue, now it's happening every day. When I first log in it's working as expected, zero issues. After about 30 minutes to an hour I now see the error stating that my connection is not encrypted, and mentions something about loading external images. I already told the support team at Tutanota that I have no images loading, but it's still showing the error. They said the connection should still be secure, but that doesn't make sense if the browser itself is saying it's not secure. It happened around the time where I also had DuckDuckGo Privacy Essentials installed as well, but I have since uninstalled that add-on. Still showing error. Please advise.

i had like 4 or 5 startup pages. i reinstalled firefox and synced twice so it could reclaim them from my home computer but nothing happened. i tried to redo it and the option is not there. not sure if this was an update but if so i hate it. i added 3 of my startup pages to the home button. so maybe i can get them from pressing that. but i prefer to have them on startup and just have one page as my home page.

When it comes to making cross platform apps, I know there's lots of solutions out there. However, It somewhat bugs me that the bulk of the ones that allow for the usage of Javascript/Typescript* for the frontend are based either on Google-developed tech (Electron, CEF, etc), or Facebook (React Native, etc).

Doing an internet search does not (easily) reveal of there are any initiatives to have something along the lines of "like Electron, but uses Quantum instead of Chromium".

Does such a project exist?

Thank you in advance!


  • Yes I know JS and TS are not as performant as C/C++/Rust/etc. That issue, (and whether to use technologies such as QT, GTK, etc.) is worthy of an entirely separate discussion that is out of scope for the purposes of this question.

With W10 set to Dark Mode and Firefox set to Dark Mode, I am unable to discern the active tab from the others at the top. There should be an outline or color difference for the active tab to make switching to another chosen tab easy. I am forced to change the Firefox Theme to one that actually does this. I don't understand why the default dark theme in Firefox doesn't do this. Will there be a change in the next version?

I can use firefox just fine (win10 home, v2004, os build 19041.1415)- I only get the XPCOM error when trying to open the Eset protected browsing window (for banking and protection). This has not happened before when using/updating Firefox and only just happened when I updated Firefox today to 96.0.2.

I've been browsing the XPCOM queries and have tried the basic reinstall (deleting program folders prior to installing) with no luck, but so far but wanted some clarity prior to trying other things-

Some of the answers here point out that security software can block the folder access when Firefox attempts updates/installs. I attempted an install with Eset paused, but no change. On another computer, a similar problem - a firefox error message occurs when trying to run the Eset protected browsing window, so attempted the same "program folder delete>reinstall" method, only now when clicking the Eset window, it just gives the loading symbol then nothing happens. Again- Firefox also works fine on that computer as well save for the same protected window usage. Not the same error, but still similar enough to think it's related.

Is a safe mode firefox install the next step forward? Should firefox be uninstalled prior to doing so? (Not just deleting the program folders via file explorer, but an actual uninstall process). Or is this something that should be breached with Eset tech support (beyond just pausing the internet protection and functionality, should it be uninstalled prior to firefox reinstall and than installed again afterwards)?

Please advise and thank you in advance!

I have a set of tabs (web pages) that I use when I open Firefox. Over the past 4 - 6 weeks the tabs all go away after I shut down Firefox. When I reopen it has a single tab. It is frustrating since I am working on a project and have to reopen 8 tabs.

It worked for many years and now it has stopped.

Help, please!
