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!!!!

There are many mainstream websites that have stopped functioning in firefox that work perfectly fine when switching over to brave and enabling scripts

these are not obscure sites, they are sites for privacy protecting entities hence the lack of function on firefox is perplexing

how do we make these sites work in firefox again to save the switching to brave?

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.

I recently got help (thank you, Cor-El!!) and was able to put Firefox into compact mode. It's still not enough. Is there anyway to make even compact mode smaller? After websites add their own headers and all, it now leaves me about 2 inches of working space; it's better than one inch but isn't enough to see things.

I've been trying to keep going back to version 99 (darker attached screenshot in blues) but it isn't being allowed. The other screenshot (lighter, in oranges and pinks) is the current version in compact mode. It's a bit better, but still is not good.

Is there any way I can change the height of the headers myself? Or can I ask someone else to do it? I'd like it about half to 2/3 the size it is now, even in compact mode. Can I do that? If so, how?

Or, can I switch things around so the headers are at the side of the screen? This is a standard 15" diagonal screen laptop currently running Windows 10.

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

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).

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

I have one Firefox profile with work and personal stuff, and am creating another profile just for work. I have exported the passwords from the first profile and deleted all my personal ones, so the Excel file just have personal passwords. I am looking for a way to import this file into my new Firefox profile. I see how to do that from another browser, but not from a file or another Firefox profile. Any help would be appreciated.

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.

Hi all,

I'm running 113.0.2 (64-Bit) on Ubuntu Focal.

I just wanted to log into my bahn.de account, got prompted with a hcaptcha which I correctly answered and then got an "503 Service Unavailable" error. The problem is reproducible each time I try. It was working fine when I last tried about 2 weeks ago. I tried disabling addons and tracking protection, deleted cache + cookies + login data as well as cookie files, reset Firefox - no change. Fun fact: The login is working without issues and interestingly even without captcha showing up in Opera and Epiphany (Gnome web browser).

Any suggestions for debugging would be very much welcome. Any hint on why the hcaptcha shows up in Firefox and not in Opera and Epiphany is much appreciated, too.

Thanks, r.

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.

Hi! My windows suddenly encountered problems and I had to reinstall it, but after reinstalling win and Firefox and logging into my account, none of my data loaded to the new Firefox. Please help, for me, loosing that much of bookmarks and passwords, is just like a matter of death and life.

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!
