Firefox Support Forum

Firefox brower is not playing videos properly.

duplicate. see https://support.mozilla.org/en-US/questions/1287469

Здравствуйте, использую устаревшую ОС WinXP*64 SP2 И максимально поддердиваемую для этого версию firefox 52, сама система и браузер стоит на SSD но всё равно происходят падения, бывают при запуске нескольких окон, а бывают при одном, иногда постоянно, иногда могут несколько минут не происходить. И вобще по часу-2 работает нормально. Чем можно протестировать чтобы найти причину?

Firefox randomly logs out of sites even when I've left the tabs open, and this week there have been problems with re-entering and resetting all the passwords. (Which is a HUGE waste of time and will keep Firefox from being my default browser when I get a laptop with enough working memory left to run anything else.) With Google and Twitter the password issues wasted only about half an hour, but with Yahoo there's still a problem. It looks as if Firefox is trying to re-enter the e-mail address into the password field even when I've typed in the password. Could this be a problem with Firefox rather than Yahoo? Please refer this question to someone who can actually go in and fix the problem, not just a "nice" Web surfer with a tip like "get a new laptop." (Though if that's your idea of a solution, feel free to send me one.)

Hi, I had Firefox on my Thinkpad T60 and it worked. I hadn't used the laptop for sometime but now Firefox didn't work, neither did iexplore or slimbrowser, they all produce the same error. I was able to find an earlier version of Forefox and it works fine but slow. Strangely when I go to goole or slimbrowser those site are found but will not find anything like amazon.com, the message from the File/properties: unknown protocal, size,connection not encrypted, address (URL): res://C:\WINDOWS\system32\shdoclc.dll/dnserror.htm#http://www.amazon.com/?_encoding=UTF8&camp=1789&creative=9325&linkCode=ur2&tag=flashpcom-20&sbSource=linksbar

The event viewer has this message: source cryp32: Failed extract of third-party root list from auto update cab at: <http://www.download.windowsupdate.com/msdownload/update/v3/static/trustedr/en/authrootstl.cab> with error: Unknown cryptographic algorithm.

This laptop is 32 bit, Windows XP.

Thank you for your help....would like to update to new firefox browser.

Hi all, I had posted in detail about a month ago the problem with FF using too much memory and CPU, but, alas, with no reply.

I'm using a much older version, 52.8.1 esr, but even that is a memory hog, on Win 7 at least. I installed this version because I've used it on Win XP before with no problems.

The current version of Chrome, curiously, uses less memory and CPU.

Hi, We were able not to display the url bar and the panelUI with firefox 68ESR but we are not able to reproduce the same display with firefox ESR 78.3.1. We are using mozilla.cfg to set browser.uiCustomization.state not to display urlbar-container in the nav-bar. We are setting a userChrome.css with those lines :

#urlbar, #urlbar * { display: none !important }
#PanelUI-fxa-status { display: none !important }
#PanelUI-menu-button { display: none !important }

But they are still here. Everything I can find on the topic is not related to the last version. Any idea to help us ?

Connection to Parler.com has failed this week. Hung up on opening favicon, and no links to the site work anymore. Parler support says this has been an issue with Firefox. It worked a week ago, not now. Any suggestions?
