Firefox Support Forum

So for the last little while, Facebook has been making a complete nuisance of itself on firefox. This isn't a browser problem, because the other tabs I have open work perfectly fine, but FB takes forever to load, and any button I press to interact with it, (like the reload button,) also lags, (but, again, works fine on other tabs,). It doesn't even register links as being clickable for a good minute after loading. The page also seems to reset every time I switch from another tab to it, showing a blank page with a loading symbol. I have tried deleting the entire history, and restarting the browser, and deactivating the adblocker, (the only extension active) and nothing seems to help. Does anybody know why it's doing this, (other than because the company follows the 'if it isn't broke, break it' theory, which we all already knew,) and how to fix it?

A white screen occurs when browsing the web. If you turn off "Use recommended performance settings" and "Use hardware acceleration when available" the problem is fixed, but then the browser slows down. Can this be fixed in another way?

Firefox 114.0 (64-bit) / Windows 11 Home 21H2

I have lots of bookmarks, which I organise into folders and subfolders. In the last month or so, Firefox will no longer save them to the folder I specify from the pull-down menu when saving but just adds them to the general bookmarks menu. To sort my bookmarks, I have to go into Manage Bookmarks and move them manually. What's happened?

I download a file. It stops and speaks of a security risk. The website is https, but the file is http. Is there a location I can pre-approve all files from the url to override the objection? Thanks.

hello! i've been having an issue with mozilla where webp images are not loading at all. this is especially prevalent on youtube, where thumbnails simply do not load, as well as on tumblr, where if an image or gif is a webp file, it will refuse to load. both are attached in the image below to see the difference between firefox and chrome, as the images load fine on chrome. as well as that, discord, when opened with browser instead of the app, does not load profile pictures, server icons, or custom emojis. google hadn't helped me at all, and i don't know what to do at this point. i don't want to go back to using chrome.

in the attached image, the top images show a set of shark sculptures. the first does not load on mozilla, and looking at the image file, it is a webp. the second image is revealed to be a jpg, which mozilla treats normally. in the second set of images, there's a quick look at a random youtuber's page, the top being mozilla and the bottom being chrome, and you can see the mozilla thumbnails do not load.

thank you for reading! i'm very confused and am unsure what to do. any help is appreciated!

No matter what I try, I can't allow any sites to present my screen or a window, I can't find an option in settings neither in the option to allow in the tab. The "allow" button is simply not available at all. How do I solve that? The problem happens in all sites that I've tried: focusmate, cofocus, discord, google meet, etc

I have Firefox Sync enabled in my Firefox browser on a few computers. When I logged in to Firefox Sync initially, it did sync-up my new computer with all of the saved bookmarks and history. I am not sure if any of my logins were saved). When I go to websites and login, I am prompted with the dialog to save my credentials, and I say ok, save. But the logins are not remembered. And in my about:logins page shows "no logins found". I don't care about retrieving any old logins, I just want to be able to save new ones and get the default behavior of saving logins working again.

I can go to xfinity email but when trying to access email it will say the service is not available right now. Before the latest firefox update I had no problem with accessing comcast email with Firefox. I can access email thru chrome without a problem. I have cleared cookies and cache but it made no difference. What do you think is going on. Thanks.

I am unable to sign into Costco.com using Firefox. I get an error message:

    "Bad Request - Header Field Too Long
    HTTP Error 400. A request header field is too long."

Turning off all extensions didn't help. Opening a private browsing window DID work. Using Chrome DID work.

Thanks!

This question was already posted and badly answered in 2016. Now things have changed a lot and Firefox DO try to translate everything which is quite annoying to anyone knowing more than a single language. No extensions related. I need to completely disable that. My firefox is up to date: 118.0.1 (64-bit).

Thank you Arturo

In the last week or so, iPlayer, All4, and Spotify (that I know of) have stopped working in the Firefox browser. All4's error suggests DRM isn't enabled, the others just say try again. Roll20 hasn't been working for even longer (more like months). They work in Microsoft Edge and Chrome. Youtube is still working, as are video players in social media.

I have tried the following solutions:

• Firefox is up to date
• Windows is up to date
• Updated graphics drivers
• 'Widevine Content Decryption Module provided by Google Inc.' is set to 'Always Activated' and is up to date
• 'Play DRM-controlled' content is ticked in about:preferences
• Checked if anything changed if either of the above were turned off (it did not)
• media.eme.enabled is set to true in about:config
• Put Firefox in troubleshooting mode
• Turned off my addons (including uBlock Origin) manually
• Tried in a Private Browsing window
• Turned off Tracking Protection
• Restarted my laptop

Nothing has fixed the problem, or given me any more indication of what is wrong. I don't know how to a) fix or b) find the problem. All I can think is that it may be related to the recent changes to Chromium regarding ad-blockers? But no one else seems to be having the same problem so I doubt it.

Coming over from Chrome (I know, I know) and so far the only customization option I'm missing is:

I'd like to be able to see the page number in the sidebar on the left (ideally next to/under each page) when printing a PDF. I work with a lot of downloaded PDFs and I frequently need to break those down into separate documents, which I do by printing to PDF in-browser using custom page ranges. For example, I'll print pages 1-2 to Document1, pages 3-6 to Document 2, and pages 8-10 to Document 3.

Having the current page number at the top of the sidebar isn't very helpful, I want to be able to see the page number for each individual page all the time so I can tell at a glance, for example, that page 7 is blank and can be skipped, or page 6 ends a report so I know which pages get printed together.

Is there a way to set this up?

Is there a way to delete a bookmark from the book-mark drop-down window (accessed from triple horizontal bar/right side of browser) but retain the same book-mark that had been saved in a folder created in Other Bookmarks? I discovered that when you delete a book-mark entry from drop down menu, the same entry is also deleted from its saved location in Other Book Marks. I was trying to reduce number of unsorted entries in drop down menu while saving (and retaining) the same link in the Other Bookmarks section and folder. I want to continue using the sorting and discrete folder saving possible with the Other Bookmark section but clean up the clutter in the unsorted bookmark section.

Hello,

I have set my OS and Firefox language to English. While the settings, menu, etc. are in English, various alerts and popups which let me save/upload a file (please take a look at the attached picture) are in the local language.

Does anyone know how to fix it? It doesn't occur with other browsers.

Thank you.

I have 3 user accounts,Admin,Guest and Visitor.The Admin User account has updated successfully from version 113.0 to Version 120.0,the latest version.When I tried to update the Guest Account and the Visitor Account from version 113 to version 120 I got a notification "Firefox cannot update automatically,download the latest version"but I already have the latest version downloaded in the Admin account.When I checked in Programs there is one Firefox icon version 120.0 and two other icons 113.0.

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

in firefox, tabs or bookmarks or anything dragable like downloads dont drag. I click and hold on them but nothing happens. I can drag whole windows, so it's not windows problem. When i restart my computer, the problem disappears for a little while but comes back.

Any help? Thank you

I don't have the option to see or edit my saved credit cards in firefox's settings, autofill still works but I can't make any changes to my cards. I went into about:config and made sure both of the below setting are set to true and they were and it's still not working, there are no settings to change the autofill

extensions.formautofill.creditCards.enabled extensions.formautofill.creditCards.available

Outlook recently made Edge or Chrome the default browser, with no possibility (as far as I can see) of choosing Firefox. In Outlook FILE/OPTIONS/ADVANCED, it seem impossible to choose Firefox.

How can I make Firefox the default browser. This situation occurred after recent update (October 2023).

Any help would be appreciated. -- JGS
