Firefox Support Forum

I've been using Firefox Developer version for some time now on Mac OS and have never had a problem like this before.

However, since version 80, Firefox Developer fails to render the new css after a change and save has been made to the style sheet even after multiple browser refreshes. Caching on the server end has been disabled so I'm really trying to find a solution to this issue as it has forced me to find alternative browsers to develop with like Safari since Firefox Developer has become unusable for me.

I've gone through and performed manual cache flushes on the browser from the settings/preferences panel. On occasion, by quitting Firefox Developer edition and relaunching it will then render the new changes but only after a quit and relaunch and sometimes using a private window as well. This is happening with multiple hosting services so it's not any particular provider.

This is most annoying. I've even reset Firefox Developer a number of times to default settings without any extensions etc. and still the problem exists.

Earlier version of Firefox Developer don't seem to be exhibiting this problem. I'm not running any proxy's or special configurations with the settings either.

Any assistance to finding a workaround would be greatly appreciated or I'm going to have to stop using Firefox Developer version altogether.

Thank you,

Last night, I noticed that the usual Dock icon for Firefox developer Edition had changed from Blue Fox to what looked like the App Store brush/pencil triangle. I restarted but it persisted. Removed the application and re-downloaded and re-installed, but same issue. I then noticed that all the Tools -> Web Developer tools had gone from the menu. Likewise, doing Firefox -> About inserted 'about:preferences' in the search bar, but nothing else happened. Tried launching the settings from the right side hamburger menu, again nothing happened.

Read around a bit, and deleted one of two profiles from ~/Library/ApplicationSupport/..., then tried re-install and restart the Developer Edition, but that complained that a profile was missing. Restored the profile I deleted, but same problem as before.

I'm stumped. Can anyone help with this one please? I'm on Mac, latest version of Mojave.

Thanks

Not a serious bug, but firefox warns about cancelling downloads when trying to switch profiles without actually exiting the browser. Please take a look at the attached image.

If I somehow click on "Cancel 1 Download", it does nothing, just launches the profile I am launching. So the warning actually means nothing, and should be removed.

Thanks.

I've got multiple clients set up to sync via FF sync. Some are older, some are newer.

However, looking at the newest client (set up ~2 weeks ago), I noticed something: It only shows a browser history up to approx. one year in the past. I've checked other clients. My oldes client goes back to ~2016, which is 4 years form now. I know my oldes client is older than 2016, so there has to be more.

Does FF Sync skip older entries? IMHO I'd have to see the exact same history on my older client than on my newer client. That is not the case. Any ideas?

Every time I open Firefox, a javascript from IcelandSue.com tries to connect to the internet. I've refreshed Firefox, cleared the cache, used NoScript to block this script, but it always remains. I've found the site listed as a Data Miner and would like to delete it from where ever it has installed itself inside of Firefox. Thank you, jason

Firefox not loading https pages, Internet Explorer 7 will load http but not https pages using xp sp3 ( I know!) I have reinstalled xp from disk etc thinking it was malware but problem remains and although IE can load any http pages it cannot load any https. I checked the certificate store and there are certificates dated up to 2028. Any ideas welcome

How do i disable autoplay on all websites - even for muted videos?

I can't disable it for all websites by default - i have to set-up individually for each website. It seems that these settings are stored in cookies, because after clearing cookies i have to set it up again.

Hi,

Fresh install of Linux Mint 19.3 "Tricia" MATE 64 Bit and I seem to be facing some odd graphical glitches. I have looked on Google and found many links to the same issue and many of them are either "Disable hardware acceleration" or "upgrade your drivers".

I have turned off hardware acceleration, and I still get the issues, I can't update my drivers as I don't have a GPU only CPU.

I don't get any of the graphical glitches on Chrome or Mint itself, and it's only Firefox itself. I have tried the "Refresh Firefox" and same issues as well as running in safe mode.

Hopefully, someone here can advise me on a fix as I don't want to use Chrome since I use Firefox sync a lot.

Thanks!

Since about version 78, Firefox started randomly deciding that both of my addons are no longer verified and disables them. I have had to reinstall them from the Firefox addon page dozens of times at this point. I uninstalled and reinstalled Firefox and that did not help. I'm using Offline QR Code Generator and uBlock Origin, which both come from the official Mozilla page. Using Firefox 80.0 now and this is still happening.

I am a student that use Firefox everywhere and for everything, but the only problem that I have ever had is this now, I was required to use Ubuntu linux for computer networks and I decided that I am going to use this OS for my entire course as my main OS, but problem is that I cannot see the videos from Echo360.co.uk which is a site that we use for our online lectures. Please fix this bug and don't make me install some trash (chr) in my pc :D
