Since the task limit option seems to have been obliterated? I believe the many more "programs" and the events they create for windows to handle is causing all sorts of virtual memory problems. Changing win10 advanced system settings from performance for programs to background services seems to have restored Firefox performance in my case, see: 10 advanced system settings win10 advanced system settings performance programs vs background services Is there an about:config option that would allow one to achieve the same "programs" limiting option as before? This laptop has 16 gig of memory and I used to successfully have even better Firefox performance with windows virtual memory turned off, but eventually I would get crashes. I can understand why Firefox was modified in a way to better localize the source of crashes, but in my case it has degraded performance. Thanks Mozilla for a great product I have valued for years!!!!

I'm having a problem using my bank website with Firefox - I get a message when I move from one page to another, and that message closes the bank website - Here is the message: "Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." It is very important to me to be able to view my accounts and investments daily - please help me solve this!

I wrote this on 13 June 2022: ...I am signed into a Firefox account. I have used this account on at least three different computers. I have downloaded the application anew at least a dozen times.

Firefox randomly, from where I sit, opens things in French rather than English. How can I keep it in English unless otherwise specified (I occasionally want German or Japanese)?

Thank you...

None of the suggestions worked. I reported that, but the thread was archived rather than answered.

How can I get all the info out of my account and try to start another that speaks English reliably?

Thank you.

tried searching for this but unfortunately i didn't find any relevant posts

When I log in, refresh, or just open up the website, I'm met with an error message attached below. I use a HP Pavillion Laptop, Windows 11, and am on version 113.0.2 (64-bit). I've tried the following: - Make sure spotify is up to date - Restart my router - Make sure 'Widewine Content Decryption Module provided by Google Inc.' is enabled. - Allow Firefox to play DRM controlled content - Disabled my plugins - Tested this on other browsers (they work) - Made sure I'm not using a VPN. Oddly enough, Spotify's web player seems to function alright in Private mode and the app is fine too. I will try any all solutions presented, please.

I have been using Firefox 52.9.0, and I know it is outdated but it still synced until a few days ago at least. Then the other day I updated my password to strengthen security. After that, I am unable to sync anymore. Is there a way to fix it? I need to continue to use Firefox 52.9.0. Please note that I do not need to be told about security issues as I am aware of them well enough.

I get the following message when I try to make Firefox to sync:

> Blocked by Content Security Policy

> This page has a content security policy that prevents it from being loaded in this way.

> Firefox prevented this page from loading in this way because the page has a content security policy > that disallows it.

Thank you.

I go to youtube, open a video and the audio plays just fine, except there is no visual. The video says its playing and I can hear it normally but I can't see anything. Subtitles show up, but the place where the video is supposed to be is just blank, the same as the background of the page. Weirdly if I click the settings button on youtube, the one next to the sign in or account button, the video will display as long as that menu is up. If I close the menu the video goes away.

I have refreshed firefox, deleted and reinstalled firefox, removed all my extensions, turned hardware acceleration off (and then back on when it didn't work) as was recommended in a similar post a few years ago, and restarted my computer. Youtube still won't show me a video. It works fine on chrome, just not firefox.

I uploaded a screenshot of an ad, which doesn't play but shows the outline of the video player, a screenshot of a normal video where the area the video should be in is just more indistinct background, a screenshot of the video appearing normally when I have the settings menu open, and a screenshot of the captions loading properly over an empty void.

Edit: I installed the Enhancer for Youtube extension? Which I haven't ever installed beofre? And now Youtube works? Why

2nd Edit: Its broken again. I changed literally nothing, just restarted my computer for an update but im getting blank screens again

I just got an add-on called LMMS Music Studio. But every time I click on their icon I am taken to something else called "https://www.offidocs.com/edit-lmms.php?username=810908&fileurl=newfileoriginal" Any ideas?

Hello At the moment I is not able to log into an official Spanish WEB-site using Firefox version: 113.0.2 (64-bit) /Windows 11. I have sent the following question to the certificate issuer (accv.es):

I have a certificate issued by you which is verified OK. It works fine with:

https://sede.agenciatributaria.gob.es

https://www.suma.es

but with dgt: https://sede.dgt.gob.es/es/ I get this message when trying to log in to 'mi DGT': XML Parsing Error: no root element found Location: https://sede.dgt.gob.es/es/mi_dgt/index.shtml Line Number 1, Column 1: Can you help find the solution to the problem.? I can not find a DGT-contact to ask for help Best regards Morten Brinch

Accv.es have so far not given me any clues to what I can do.

Anyone having suggestions how to fix the problem ?

best regards Morten Brinch

Im using Firefox desktop version 113 with win 7 Browser will not save logins or passwords either saved by me manually or by importing from chrome.

Below you will see the screen from my settings after saving. Strangely, I do get the prompt to save them. See other image below.

I do not want to use sync. I only want firefox to store this locally as the earlier versions did without any issues.

Thanks

Hello,

My bank's website has a 2 page verification process for logging on. The first page is for the User ID and the second page is for the password.

Until just a few days ago, I could enter the first letter of my User ID into my bank's website login field, and FF would auto-fill the rest. Now when I enter that first letter, nothing happens. I then have to look up this info before I can continue. Luckily, the second page (for the password) is working just fine.

If I remember correctly, there has been a recent FF update. This new update may be the source of this issue.

Please help!

Thanks, Andre'a

Hello - Firefox to Safari bookmark syncing used to work seemlessly between pc and ipad. Noticed it's no longer working. I've done all the resetting/restarting/logging out/uninstalling/reinstalling recommended. It still won't sync. I ended up installing Firefox on the iPad to get the bookmarks from PC. That sync works (takes a while sometimes). But it will not ever update the IOS from the last time it worked (maybe 3 months ago). I can erase IOS bookmarks and reload from iCloud, but the files are months old.

Has this function just been removed?

Hello:

I have 2 profiles in use. 1 for personal use with their respective bookmarks, passwords, and extensions, and I have no trouble syncing with this one. However; profile 2 that is for work use that has its respective bookmarks, passwords and extensions, has become a nightmare.

It happens that I have both profiles on the same computer and when trying to create an account in Firefox, the system asks me to enter the email registered in profile 1, with the warning that bookmarks, passwords and extensions will be mixed.

I mention that I have migrated from Google Chorme to Firefox for speed reasons and because I use windows 7 (I don't like later versions) Now well; in Google Chrome you could create as many sessions as were registered but in Firefox you can't.

Oh! I have been working fine with Firefox but suddenly an error occurs (it has happened to me 2 times in the last 2 months) in which the program closes and all the data of my profiles stored on the pc DISAPPEARS or is deleted (including cache), when I want to open them again:

firefox.exe -P

Then I have to give myself the task of synchronizing profile 1, but profile 2 I have to be importing from my previous Google account or importing a backup Bookmark.

The option to copy and paste the data from Firefox to replace it in the path (supposedly brings with it the data of everything):

C:\ProgramData\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38\updates\308046B0AF4A39CB

with Firefox turned off it has not worked for me. Since when opening I see 2 profiles called Default "X" and Default "Z" without data.

This is a headache that if it happens to me, it happens to millions who have 2 or more profiles.

Why can't I sync a second profile? Why do you insist that there can only be one sync per device? Is there a solution for this?

Note: I have read all the tutorials out there and the situation remains the same. Synchronization with 2 or more profiles is never described.

Thank you very much to whoever asked this question!

My preferred languages are set to: en-us, en, ja My preferred fonts for Japanese are set to: proportional: Sans Serif, Serif: IPA 明朝, Sans Serif: IPA ゴシック For web pages that set the language to Japanese (using lang="ja" or similar), the correct (Japanese) font is selected. However, for web pages that do not indicate the language, Firefox selects a Chinese font, ignoring my preferred language and fonts.

New version produces "Access Denied" when logging into Chewy.com Please fix this. I tried to add an image, but, like last time, doing so froze the page and I couldn't get back here. Had to start over. Can I revert to the earlier version of Firefox that worked? If so, how?

When watching something on Youtube and I click on the coloured download icon, I get to be able to click on the title of the video. A blue 1 appears in the download icon. When I click again, then click on the blue 1 to watch the download. Nothing happens. The window just sits there and states 'downloading', but it does not happen. This happened last year and you managed to fix it; now Youtube seem to have blocked downloading again. Geoffrey D Dean, Australia.

G'day Folks,

I have an issue whereas Firefox 113.0.2 does not display website correctly using Win 8.1e or Win 10 Pro. Firefox 113.0.2 does not display website correctly The site has a Date and Time line with a colour line underneath it, "The current AU EST Date and Time in Tanilba Bay Australia is - June 1st, 2023 2:34:07 PM" "PC-Bug Fixer draws the line" that refuses to show centred.

Google Chrome, Internet Explorer, Bing, etc. all show these items correctly, i.e. centred under the headers above it, but not Firefox 113.0.2.

I have deleted all the History, cache(s), etc., but reloading still fails to show these items as being centred.

Any Ideas please on what I have forgotten to do to fix this anomaly please?

Regards Roger Hass / PC-Bug Fixer now in Tanilba Bay NSW 2319 Australia
