Firefox Community Forum

Preferred Firefox for most of my online use in my 82-year career in the ICT space - why has it deteriorated so badly? Am using Chrome for now, works perfectly, doses not freeze up my browsing or simultaneous use like Word or outlook. Should I abandon Firefox and switch to Chrome permanently?

When starting Firefox after a PC startup or restart in Windows 10, Firefox will lockup and exhibit a "Not Responding" message. Windows will then show a "Close Program" or "Wait for the program to respond" choice. This happens on any of my machines, Windows 10 and 11. It's to the point of wanting to uninstall it. After it finally loads the first time it loads fine on subsequent loads.

My Desktop - Win10, 260+ Gigs RAM/14+ TB HD space Firefox updated a couple of days ago, and again today (this time to 155.0.1) Ever since . . . . . . Having Major problems NOW No Rt-Clk function in Ff Ff menu buttons non-functional Ff tabs can no longer be rearranged Data entry fields, dropdowns, Submit buttons, & "add to cart" buttons not working on Ff pages -Things I've tried; I rebooted Ff & Windows several times each - No Joy I cleared Ff startup cache twice - No Joy HELP! I use Ffox for roughly 85% of my online activities - I'm pretty much hosed

PLEASE HELP!

i have tried anew profile got a the newest version and it still does not help i guess the people doing the updates have no idea how to fix the issue or care none of you can really help all the idea you have had i have tried and still i get the same Firerfox running but not responding' guess you will force me to go to chrome instead which does not do this nor does Edge so you can not tell me it is not a firebox issue because neither Chrome or hedge with by the way all the same desktop icons i have had for years work

I log in get a dead home window cannot delete , no response to cursor have to use task bar icon to overlay dead home screen. when return to home scree I get the dead old window and use task bar icon to get live home screen to continue. The dead home screen appears and have to select firefox from task bar each time.

So I know these websites are kind of crap anyway, but I have issues with scrolling bsky.social (and other clients for it like witchsky) and twitter. The further into the timeline I get, the more frequently these webpages lag.

They begin freezing every few seconds for a few seconds, during which they queue left or right clicks, page up/page down, and various other commands, only processing them once it unfreezes. Firefox itself still works during this freeze, e.g. opening the main menu. Also, I can still scroll up or down to a limited degree, though this just exposes empty, unrendered webpage until it unfreezes.

bsky.social has had this problem for a long time, but twitter only recently developed this issue after I had to do a cache clear, cookie clear, etc. trying to log in a few weeks ago. Prior to that it didn't have this issue.

Task manager hasn't really helped elucidate what's wrong, so it might be an about:config that I set or even an unruly extension, but I really don't know what to try.

u have asked how to stop Firefox from keeping saying firefox id running but not responding. I have gotten some answers but i need to let you know this is what i have in my task manager you will se the photo there is also one at the top plus i have all these profiles the one in bllue now i saw where it said to place.sqlite and rename it old i also took out parent lock and it is still happening all the time so what can anyone k help me stop this

For at least a few months now, my browser will suddenly and randomly go fullscreen all by itself. I can't exit it, and then it goes back to normal after at most a minute. It hasn't happened in at least a week. But today, it froze like that, not responding. I quit firefox, waited a bit, then restarted it. It went fullscreen and froze again. I waited at least 10min and it then went back to normal and responded again. It only happens when using firefox. I've done virus scans, etc, and it still keeps happening. Please help. Thanks.

I have a Windows 10 Pro system and Firefox continues to open up at least 17 processes for one internet window. This eats up system resources for nothing more than general web browsing. How can these processes be limited? Thank you.

Hi! We have automated tests that run in Firefox across a large number of instances. There are about a hundred nodes where the browser is launched. For security reasons, there is no Internet access. When the browser closes, requests are sent to 146.75.117.91. Since there is no Internet connection, the request fails to complete, and the process terminates due to a timeout. Because the browser is controlled by geckodriver, the `driver.close()` call fails with an error. I’ve tried numerous browser startup options, but none solve the problem; the process still crashes. The only thing that works is blocking the IP address at the firewall level or in the `hosts` file. However, I’m not happy with this solution because it would need to be applied to a hundred nodes, which would create scalability issues down the line. Are there perhaps any options I missed? I also found these addresses in `omni.ja`. Could it be that they are hardcoded and cannot be changed via options?

Hello, After the last update i keep seeing a blank page when i open a new tab or new page. i tried the troubleshooting mode but the same. i need to refresh every time i open a new page.

I have tried safe mode. No joy, but it has shown plain vanilla FF is the issue, not extensions.

(I'm using a different browser to make this report, so Share Data button is of no use here.)
