Firefox Support Forum

I have been using Firefox 52.9.0, and I know it is outdated but it still synced until a few days ago at least.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.

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 amazed, just AMAZED I can't find the answer to this with a simple google search, or searching the questions here, and I re-worded my search several times. All the answers I could find, even chatGPT (I know it's not alway sup to date) told me to use this option even though I specifically told it it wasn't there, is anyone aware that sometimes the option isn't there? What gives? Not blaming anyone specifically, but this a really simple question, I'm I the first person it's ever happened to?

I'm trying to fix a sound problem where videos will not play, and this is a suggested step. The sound on youtube videos plays with Google Chrome, so it's not my sound drivers, just with firefox it doesn't play. One of the steps as well was the clear my info, I cleared everything except history, I wished there was a way to back those up, I'll look it up.

Starting firefox in safe mode doesn't fix the problem either.

Long story short I've lost about 30-40 tabs and can't get them back. What happened was that my computer was being strangely slow, so I opened task manager to close some stuff with one of them being firefox. I had about 6 windows open, 2 of them having a lot of tabs, the other 4 only having a few. Reopened firefox, click restore previous session and only 3 windows reopen. I've never had this before and am scrambling to try to fix it as the tabs/windows that did not reopen are the ones that were actually important. I've tried to use the scrounger thing that jscher2000 has suggested and haven't been able to find anything (I don't know much about code tho so could probably be missing something). I don't know what to do and am panicking a little as like I said, those windows that did not reopen were important. I'm trying to figure out if firefox saves older versions of the session restore .jsonlz4 files (besides the .baklz4) but they seem to just be overridden/deleted. Is there anything I can do or am I just screwed? Also recently closed windows and tabs options are empty when looking at the history tab, which has also never happened. New update today so could it be that that has caused this problem? Finally, I've looked at the Import and Backup -> Restore option, which has worked for me once when something similar happened, and between Saturday morning and now (Tuesday), there is nothing, which is odd as I close out all my tabs every night and this morning everything was restored perfectly. Yesterday is when I opened a lot of the important tabs for the one window, so could there be some kind of glitch occuring there? Any help would be appreciated Thanks

Everything worked normally for me for 2 years, but recently i decided to reinstall windows. So i did it, downloaded firefox on raw system and now i get this error on some youtube videos. I tried everything i could find but nothing fixed this issue. It pops up with firefox account, without it, in private vindows, in regular ones, with addons, without them. I tried reinstalling firefox, i updated every driver, i use google DNS, but it still doesnt work. In edge, chrome etc. theese videos play fine

Greetings everyone,

I accidentally double clicked on "Downloads" after accessing the "Tools" menu so all of my downloads in the "Downloads list" is now gone... :(

I know that the actual files aren't deleted but I can no longer see the location of the files I've recently downloaded :( :(

Thank you for any help!

When I switch from one tab to another doesn't matter the webpage the page adjusts the content on the tab. For example I was on youtube and switched over to gmail and it adjusted the screen and when I switched back to youtube it did the same on youtube. I wasn't zoomed in or anything. I was just on the tab and it was fine and looked how it should but as soon as I switch to another tab it does it on that tab and then will do it again when I switch back to the tab I was on originally on. I'm on FF vers 113.0.2 (64-bit).

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

I know there are ways , with more clicks or longer shortcuts to get to some folders but this is the main and most easily accessible way to get to my bookmarks. I know this has been discussed in some older posts but they are all archived so I can't ask any questions there. Sorting by name, for me, is quite inconvenient as sometimes the bookmarks title isn't immediately, easily remembered. 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

Hi all Gurus,

I have been trying and searching but I could not find a suitable answer. Figured I try asking the question here.

Is there anyway or what is the policy that I can configure to disable the "New Tab Ctrl+T" function on the menu please? Attached image.

Hi there! My Website layout not properly show in Firefox browser as shown on other browsers like chrome, apple browser and others. page width shows to short. Is that browser issue or my website? Note: I used some WP plugins in my website.

In the last few days, I have noticed that a number of websites are throwing me SSL_ERROR_NO_CYPHER_OVERLAP errors. Most websites, particularly more modern websites, seem to not have this issue. As some more professional examples, www.twitch.tv and www.dndbeyond.com throw this error. I have tried setting temporarily TLS version fallback limit and min to 0, with no change. I'm not really sure how to go about debugging what cyphers these websites do support and why they are throwing these errors. Any help on where to start would be greatly apprecaited.

I use the closed captions (CC) in YouTube videos with FireFox. Lately I have been seeing videos that seem to misbehave. At the very start of the video, ALL the captions display at once, one after the other. Then, as play continues there are no more captions. Most videos still show captions normally, that is, captions appearing only when the dialog matches them. But a few videos misbehave by showing all the captions at once. Here is one such video.

https://www.youtube.com/watch?v=ZgqJ5wQF944

I noticed this misbehavior within the last month and assumed that the video was doing something peculiar with the timing of the captions. But when I use the YouTube Show Transcript option to display the captions and associated timing outside the video, the transcript looks quite reasonable.

One further oddity, if I take that same URL and load the video in a different browser, for example, Chrome, the captions are displayed normally.

I've included a screen shot of the video in YouTube showing all the captions displaying at once.

I installed Firefox at work and set my personal email address as secondary to my business address. Well, I liked Firefox so much that I decided to use it at work and at home - and I removed my personal email from my business account. Unfortunately Firefox is still recognizing my personal email as the secondary address for my business account and I am completely incapable of making a new account. My bookmarks and saved passwords are all different between home and work. I NEED two individual accounts, just like how I was using my browsers with Chrome. t

I saw an other article about the same possible but they had a problem with an extension but I dont have that extension but still have the same problem. Whenever i watch twitch or youtube and i alt tab or switch tabs my audio and video stops playing.
