Firefox Support Forum

Since uploading the latest update today many of my webpages no longer appear properly. I have given you an example of one which has the URL of https://www.newsnow.co.uk/h/Sport/Football/Premier+League/Tottenham+Hotspur?type=ts You can see from the screenshot image that is added to this message what I mean. This is happening on quite a few websites now. Can you please advise a remedy or address the problem ?

Gradually I am losing all ability to use Firefox for financial and vendor payment logins. One by one over the past year I get varying messages that keep me from logging in. Chrome (which I don't care for) works in each instance. Yesterday Vanguard denied me, stating THEY are experiencing technical difficulties, apologizing for the "temporary" inconvenience. This message has been coming in for six or seven months at login but I was able to try again and it would let me in on the second try. Recently, a Vanguard rep suggested clearing my cache, which I tried successfully last week. Yesterday, I received the same message and clearing the cache failed. I love the Firefox structure and feel, and it's keyboard shortcuts, but I can't be fooling around like this every time I try to log in. This has now happened with a number of vendor payment accounts, my banking login and now Vanguard. How do I fix this?

HI all! Hope you all are doing well.

I am using user.js file to harden my Firefox to the best possible way. I have few question about that process.

1. Where i can find the complete list of all active user_pref settings? All of the options i have to edit them. like user_pref("security.sandbox.content.level", 6); - now i have 6 by default but what is the range?

2. Is there any tool i can use to update my list with the latest entries, and to remove the obsolete entries?

3. Sandbox - what are the best possible ranges and settings for the below entries?

ser_pref("security.sandbox.socket.win32k-disable", true); user_pref("security.sandbox.content.level", 6); user_pref("security.sandbox.content.shadow-stack.enabled", true); user_pref("security.sandbox.gmp.win32k-disable", true); user_pref("security.sandbox.gpu.shadow-stack.enabled", true); user_pref("security.sandbox.gpu.level", 2);

Thanks well in advance! Firefox 116.0.3

Why do I now receive regular notifications from pantheos? They come in via modzilla firefox. They are mostly religious in nature. Why do they come to me, and who pays for them, and why?

8/18/2023 1340 Firefox ver 116.0.3 64 bit Keeper ver 16.6.0

I am still unable to use Keeper Ext. When I go to sign on screen for any of my saved websites, place the mouse in the sign on screen, nothing comes up for me to click on as before. On automated sights, nothing happens either. Can you advise estimated completion time?

This is what Keeper says:

Monitoring - We have pushed a new version to Mozilla (16.6.1) which is pending review to address autofill issues on Firefox. Aug 17, 2023 - 22:33 PDT Identified - We are aware of login and filling errors with the KeeperFill browser extension on Firefox. This issue is randomly occurring during initialization of the extension. Restarting Firefox when this occurs may temporarily resolve the issue. We have pushed a new version to Mozilla (16.6.1) which is pending review. Mozilla should release the update within 24 hours. Aug 16, 2023 - 11:24 PDT

Hi, As of last 2 days (since the last upgrade) Firefox does is stuck on some sites. Some features on facebook would not load Some sites say that the servers take too long to respond - say they have troubles reaching servers. Some sites refuse to login or stuck (chesstempo)

Note then I tried all this on Opera - all worked. What could be the issue? cleaning cache did not help.

thanks, Mark

I am signed in with this email on another computer. The only idea I have is firefox is rejecting the email format before even checking the email.

Please help, thanks.

Firefox 116.0.2 64bit on Windows 11 Pro 22621.2134

I noticed today that a video hosted on the website Reddit has subtitles on it. When I view the video in other browsers it does not have subtitles. Why are subtitles being generated in Firefox for this video? Is there a way I can disable these subtitles? While often useful, the subtitles in this case just get in the way.

If URLs are allowed one example is here: https://v.redd.it/z7tekckuy9hb1

Thanks.

The last Walmart questions are 2022, so again... When I click a link to Walmart, for a second I see the full site displayed correctly on my desktop monitor, then it shrinks to about half to the left side. Windows 10 up to date, Firefox 116.00. Enhanced tracking, whether on or off, doesn't matter. Walmart is the only site I have this issue with. Is it Walmart's fault?

Hi everyone,

I have permitted a website to access my location, but Firefox is not retaining the settings. While I am on the web site I keep getting the "Allow www to access your location" popup several times in a row and the website still reports that I need to enable the option. This is happening to all websites, not only this specific one.

What I have done thus far:

Restarted Firefox Refreshed Firefox Rebooted my computer Cleared Firefox cache and cookies Confirmed under Settings/Privacy & Security/Location that the site www status is "Allow" Removed my ad block settings from my router as I don't use a local add on

I am using Firefox 116.0.2 (64bit)

Thank you!

I had about 100 tabs open but when I opened up my bowser they had disappeared from the 'Recently Closed Tabs' list and the vast majority don't appear in my History.

How do I recover the Tabs?

TIA

Whenever I use amazon prime to stream video after watching for several seconds the video quality is throttled, this also happens to youtube videos but mainly effects FPS and only when im tabbed out and using my second monitor. I am 100% sure this is not my computer or wifi as both are very good and the problem does not persist when I swap browsers.

When posting on vBulletin forums, Firefox (116.0.2 on Windows 10) inserts and extra line upon pressing the Enter key. The fix for this is reported on the 'Net to be to alter variables in about:config.

I've attached a screenshot of settings on my system as reported by about:config. My questions are . . . 1) What, exactly, does the bottom line in screenshot mean? If I display All in about:config I find no Newline entry? What effect, if any, does changing values among the choices do? Do they affect the other settings? How? 2) What effect do the other 2 settings as shown have on entries typed in Firefox? 3) Are there changes that I should make in the top 2 variables that will stop the extra line insertion?

TIA

I'm developing a PWA website that relies heavily on the sqlite.org wasm libraries and origin private file system (OPFS). On firefox-dev 116.0b8 my website at app.kumaflash.com stopped being able to read the database it had been successfully using for months prior to that. I've also asked on the sqlite.org forum here: https://sqlite.org/forum/forumpost/3bb8b83c45 but haven't found any solutions yet.

You can see a thrown together video of the app working normally here: youtube.com/@kumaflash

and the error I receive is: OPFS syncer: xRead() async error: GetSyncHandleError: Error getting sync handle for xRead(). 6 attempts failed. kumaflash.db : NotFoundError: Entry not found

If I manually open the OPFS in the console I can see that the file is there with this helper function in my app: var p = await _app.xdcards._lsOriginPrivateFSDir("/"); //that's an L for list ListOriginPri...

Additionally I can't debug because the firefox debugger crashes whenever I try to inspect my app. The debugger crashes on firefox-dev and release versions on every computer I've tried (with this app only). The chromium debugger works but the error doesn't happen there.

Any ideas on what I should try?

After installing Firefox 116.0.1, I find that while browsing websites I must disable AdBlocker Ultimate to view products on some sites. This was not a problem in previous versions. Oh, I just tried doing a search using DuckDuckGo and results were not displayed unless AdBlocker Ultimate was disabled. Other than allowing all ads on all web pages, what can I do to correct this problem? Thank you.

Last October my sessions were gone after a Firefox Update. I asked for help here: https://support.mozilla.org/sv/questions/1394685 and eventually got kind help from @cor-el (that unfortunately wasn't skilled enough to understand) and from @RayGibson57. But by then, my life was in a flurry and I didn't have time to try the advice. And so, after a while I had, with some effort, gathered many of the old tabs back again, and built up new sessions.

This Monday I was trying to internet while having high fever (something people should never do :o ). I left three blank windows open when I shut down the computer, and next morning those three were the only ones Firefox wanted to remember.

(I still find this change frustrating, bordering on infuriating: what happened to "Choose how many old sessions you want Firefox to remember", I think the maximum was ten?)

Now the fevers left and I went to those answers to try. That Q/A was archived though, so I'm starting again here, from as far as I got following King Rays instructions. They were:

1. Open the application menu (3 horizontal lines) next to the address bar.
2. Click on Help -> More troubleshooting information.
3. With that page open, find Profile Folder and click on Open Folder. That's how you get to the folder with backup files in it.
4. Set computer up to see all the extensions & system files. By default, the extensions don't show up (.jsonlz4 is an extension).
5. I found an older file in that sessionstore-backups folder and copied it one level back to the main profile folder.
6. Renamed the sessionstore.jsonlz4 to sessionstore.jsonlz4.old and the file I copied, I renamed to sessionstore.jsonlz4.
7. Opened Firefox and that missing window was in the history so I could open it.
8. Don't make any typos here, because Firefox won't find the files it needs to open.

I got as far as finding the Profile folder and the sessionstore-backups folder.

But I cant find any jsonlz4 file called "sessionstore". Only a "sessionsCheckpoints" and that one is a json file, and the date modified is today.

See screenshots please!

Can anyone talk me trough this like Im a grandmother from Sweden with extremely limited coding & tech skills (which is what I am)?
