Firefox Community Forum

First the laggy, extremely slow issue was just noticed on YouTube. Now I notice it on Rumble and other sites. For now, I have to abandon Firefox and use an alternative browser. I've stayed with you for years. Maybe it's time to part ways. I really like your browser. But, it has become nearly non-functional for me.

Adobe auto updated. The ability to choose where a PDF is opened or downloaded is now missing. Completely makes FireFox unsuitable for what I do.

I did redo all the settings to 'ask before'. Refreshed FireFox. Tried changing it in the popup where I choose what to print.

What do I need to fix?

Albertsons grocery store states they support firefox. However I can't use firefox I have all sorts of issues so I have to close firefox and use chrome. What do I need to do to get firefox to work at their grocery store website?

Thank you Diana

Hello, this is the basic problem:

The short version is that there is a problem with Firefox not interacting with the scrub bar and volume bar. (all other controls work fine) We know it's a Firefox thing because everything works with Brave. (or an interaction between Firefox and the OS at least, Firefox is heavily involved)

There is more detail and we have done some work on it here: CashyOS forum post

You can use the Firefox manifesto V0.2. video for an example, as it displays all the above problems for me.

I can get you guys whatever other data might be needed, but I kinda need an idea where to look to try and fix this, as all the other posts I have managed to find don't seem to have similar enough issues to work.

Edit/Update: I have done some further testing and discovered that it is firefox's default/built in player that is the problem. I can use the 'site specific' players (like from reddit) just fine. So there is something happening with that default one.

new update destroyed old firefox look i love those old sqarish tabs please give us option to switch back to old firefox look, themes, styles... in settings, i dont see it anywhere, the tabs were perfect like they were new look of tabs is horrible (at least to me) is there some way to return to old look. Ai said to me to play around with a userChrome.css file but i still cant get the old look no matter how much i try, it gets worse and worse, worst case scenario is it possible to send me a css file of old tabs / toolbar look or something i feel like someone moved every single furniture in my home, the feeling is terrible. new icons are okay but old toolbar and even search bar is better in older version, i loved more the old look why is there no option to revert back to old theme look i used for years.

HI All Recently purchased a laptop and want to have FF sync with my desk top. I am signed in to both devices with the same account and have checked all settings on both and they are identical. Why are they not syncing?

Hi, since the latest update, whenever I'm in a tab (e.g. email or personal website) and I go to upload files, all tabs show the last location of the last upload from any tab whereas previously they showed the location of the relevant tab. E.g. on a tab for my website it would previously open the location of my website files and if I switch to my email tab it would open the location of my email attachments. Now it doesn't seem to remember the loaction by individual tab it just starts in the location of the used loaction across all tabs.

Not sure if that makes sense, it's very annoying as I have to keep searching the location again between tabs.

Can this be changed back please so it remembers locations on a individual tab basis and not globally?

Thanks

Is there a theme or some other way to restore the classic styling instead of having these pills everywhere? This UX doesn't even make sense...tabs used to connect to the page content they were displaying, now it's just some disconnected oval; I have trouble seeing which tab is selected now because it's all various shades of grey that are about half a bit of luminosity away from each other...looking for suggestions on the best way to restore some sanity to this UI...

So PDF's can no longer be set to open in Adobe, but it now requires clicking before the document opens in Adobe. No setting whatsoever can change this. Is this a permanent setting? Will have to move to another browser now. What a hassle. Got to move bookmarks, set up home pages etc. Ugh. Bey Firefox....

Hello,

I have had an issue for a few months now where certain websites fail to load. This is most easily reproduced on https://addons.mozilla.org, where I am shown the error "An unexpected error occurred" on most pages, preventing me from installing addons.

This issue does not occur in a Private Window, in Troubleshooting mode or in Chrome or Brave, but persists in fresh installs of Firefox. In troubleshooting this issue, I have removed all program files, registry data, and app data pertaining to Mozilla / Firefox. In fresh installs, I can sometimes install an add-on or two before this error starts occuring. I have not imported any previous data.

I was previously installing from Chocolatey, but in my last clean install, I downloaded from the official website.

I am on Windows 10 and Firefox 157. I use Proton VPN (Paid) and have tried changing servers several times to no avail. Again, this only happens in Firefox in a standard window, Private Mode and Troubleshooting Mode are fine.

Screenshot 1 shows the issue from my most recent reinstall. I was able to install 1 add-on (SponsorBlock) before it started showing up. Removing the add-on doesn't fix the issue. Trying to access addons.mozilla.org via a search engine results in the tab icon loading for a second and no change happening on screen (Screenshot 2).

I experience similar issues on other websites, like trying to log into Bandcamp.com (logging in gives the error "There was a network error. Please try again."), but most sites work.

Loading https://addons.mozilla.org/en-US/firefox/ gives the following results in the Network Console:

Uncaught (in promise) TypeError: can't access property "pressed", target is null

Firefox tabs keep crashing for no apparent reason after this Nova update (its not website specific). here's a list of my top five Submitted Crash Reports (there are dozens more but ill keep this brief): Report ID Date Submitted

i don't believe its memory issues because my PC has 61.6 GB of 474 GB free, and i never got these crashes before the update, with the same amount of data. dunno what else to add here, let me know if i need to provide something more

At one point earlier this week, I had to sign out of all but one of my google accounts to get a link for a remote meeting to work. Afterward, when I visited youtube, it logged me in under that google account, which is not the one I use for browsing on my own time; I logged out, then, when I tried to log in under the proper account, google/youtube thought erroneously that I had set a passkey, and it and my password manager fought. I fixed the conflict (deleted the unset passkey). Then Youtube stopped letting me log in; no matter what, I get sent to www.youtube.com/oops

Initially, this error effected youtube login on all every browser I use. Clearing the cache and history on those, after having fixed the password issue, fixed the problem on them. Firefox, however, is refusing every fix.

I have cleared the cache, the history, going back to 'Everything.' I uninstalled and reinstalled the browser. I have disabled all add-ons and enhanced tracking. I have gone into the advanced configuration settings for firefox and deleted the cookie files for my profile. Youtube and Google are ON my security whitelist. I've tried "forget about this site." I've tried private browsing after first clearing the cache and history, "forget about this site", and after deleting the cookie sqfiles.

It has been days, and I am going in circles! Can anyone please help me?

Every time I ask a question, it immediately disappears; i.e. if I refresh the page, it says the page doesn't exist, and then I go to "My Questions" and I don't see it there either. I'm sure this one will be immediately erased too. What is going on?

Firefox just forced a terrible update on me that makes everything look round and different and I hate it so much. I don't understand why they think people want things to change all the time instead of being allowed to get familiar with something and now have it change on you without even asking if you want it to change!

Hi guys - I am running Firefox 157.0 (aarch64) on a Macmini M2 pro with 32GB RAM .

I am regularly receiving messages that my default browser, Firefox, is the largest consumer of that RAM. This is what I received this morning shortly before my system shut itself down. I did have many files open but noticed that Firefox is consuming 33GB of my RAM. Is this normal?

This morning, I can no longer download (Save) files to my computer, nor check/change settings in Firefox. Tried all troubleshooting steps to no avail.

If I delete and reinstall Firefox, will I lose all my Bookmarks, etc.? Running version 157.0 (aarch64).

Appreciate any help!

After a while bookmarks disappear from the browser tab and the only way to recover is to close the browser and open a new page that requires signing out of opened sites and starting over. Just started with new update release.

Hi, my spell check only rarely works, I have tried adding more dictionaries, but as it works sometimes, I assume it is something else that is the problem, I had asked about this in another thread, but cannot find it.

So basically if I right click there is no spell check option most of the time. I have also installed LT check spelling and Grammer, not if that interferes with spell check, I feel I had this installed after the problem started, I tried disabling it, but spell check still only activates intermittently.
