Diễn đàn hỗ trợ Firefox

I've tried refreshing Firefox, restarting with add-ons disabled, uninstalling and reinstalling multiple times, and tens of other things that I've forgotten about by now. If anyone has any idea how to fix it I'd really appreciate it, even if it doesn't end up working.

I am running Windows 10 and I use firefox for internet access as my browser. Things drag on when I open Firefox. And then I check Task manager and I see, 4, 5 sessions running, all dragging down memory in a big way. Slows the my PC. I am on the latest update and also have done resets. But that does not fix it. Any idea of how to only have Firefox run a session only when opened? And not fire up multiple sessions even though I only started one browser session? Thanks very much

Hi all,

I've been having problems with firefox lagging constantly. General browsing around feels laggy - and opening new tabs pretty much causes my computer to freeze for a few seconds. During this time firefox causes the CPU to spike to 100% usage.

I've been using firefox for years on this computer with no issues. Hardware is pretty good (i7 5820k, 64GB of ram and an SSD).

So far I have tried:

• Running in safe mode

• Using a different profile

• Downgrading to an older firefox

• Changing allowed CPU cores from 8, to 4

• Updated graphic card drivers to latest version

None of these work, and I'm getting a bit tired of the constant slow downs. Chrome works flawlessly, as does all my other software...

Any ideas?

Thanks!

This is a portal which my college uses for assignments and deadlines but I am not able to open it on my desktop. I have tried reinstalling Firefox but it didn't help. No other site has this problem in Firefox. This site opens normally in Google Chrome and Falkon. I have attached a screenshot of the error message. Thank you.

Hi all, seit Kurzem (leider weiß ich nicht genau seit wann) stelle ich fest, dass Youtube Videos (Wiedergabegeschwindigkeit Standard) unter Firefox (Windows 10) zu langsam abgespielt werden. Das ist sehr irritierend. Ich habe das Windows Media FeaturePack installiert und unter Chrome läuft auch alles normal. Ich hab mal ein Video von der Tagesschau von einem anderen Portal gestreamt und auch das scheint normal zu laufen. In Youtube habe ich das browser.sessionstore.interval angepasst. Ohne Effekt. Cache in Firefox gelöscht - ohne Effekt. Bin ratlos. Hat jemand eine Idee? Best regards. Joachim

I am having a problem specifically with PNC's website. FF 85.0.2, Mac OS.

I can get to landing page. After attempting to login, it shows this message:

"Please try using another internet browser. If you still receive this message, please call the Customer Care Center at 1-800-762-2035 and reference code: 18.84386368.1613484239.62933e90"

I can get the site to load in other browsers, and on my work computer (Same build FF, but Windows 10)

Attempted fixes: Turn on Safe mode Delete cookies, browsing history, cache Uninstall Norton Anti-Virus Refresh profile Forget about this site (which I have FF set up to delete cookies, history, cache on close, but manually re-enabled history and tried this as well) Attempt to browse with Private Mode Off, all tracking settings off

I have thought about uninstall/re install but if my profile is the problem, don't know if this will fix it.

Installed plugins noted.

All things I try to download on Firefox are extremely slow compared to other apps like Steam, torrents and other apps. I get 90mb/s on the download speed checks, but when I try to download something on Firefox, it downloads at like, 120 KB/s.

I am having issues with Firefox browser on my university website. When I do a search in the ebsco library and I try to advance to the second page of the results nothing happens. When I try to modify the search terms it returns me to the original search terms. Also, in the classroom portal called Brightspace I am unable to see embedded video clips.

These issues never occurred in the past versions. These issues do not occur when I use Chrome.

Each time I start FF 85.0.2 I must reset each web page custom zoom setting as they are not saved from the previous session. I have carried out a refresh to no avail. I have reinstalled FF without any improvement and History is set to 'remember'. I set some zoom levels whilst in safe mode and restarted but no better. What can I do to fix this problem?

Hi. I am trying to reach a site that I have in the past found a good reference site (if you like reptiles), Ian's Vivarium. I am in up-to-date Firefox for Win10, I have refreshed Firefox to no effect. Error message on the website is: "You are running an unsupported PHP version. Please upgrade to PHP 7.1.3 or higher before trying to install or update to phpBB 3.3" at the top of a wholly blank page.

I get the same error when attempting Chrome and Edge (which crawled back onto my PC uninvited)... maybe a website issue?

Help?

While not totally computer illiterate, I'm pretty close....

Thanks in advance?

I do use Eset. I have cancelled the master password ,closed Firefox and then restarted it to put the master password option back on but the problem persists. It is happening on all the pc's in the household. Using Windows10.

I recently couldn't logon to my local online banking site. The thing is, is had been working just fine for years, and then all of sudden stopped working. Upon calling the bank they said everything looked fine on their end and try using a different browser. I used Chrome (would rather NOT use that browser), and I could logon fine. I found that if I disabled Privacy Possum it worked fine, so, now when I want to logon to my local bank I just disable Privacy Possum and it works. But I don't understand why it all of sudden quit working.

Now I can't logon to my Penfed credit card account. I tried turning off all the extensions, NO help. I went to the Firefox trouble shooting section and refreshed Firefox and did what ever else they said to do like clear ALL my history and cache...still no help. My Penfed had been working just fine until today, and it also comes up fine using Chrome. Is there anything that has changed in Firefox that is blocking my two online banking accounts that you know of?? This seems very strange.

Hi there. I have a feature that I would like to see on Firefox (Pinch zoom on touch displays in the Firefox PDF reader).

So what I did I searched for the best possible way to submit my feedback. I belive to have found it under Help -> Submit feedback. But upon clicking this button, I get immediately redirected to this page:

https://qsurvey.mozilla.com/s3/Give-feedback-landing-page

which undoubtly seems like a redirect error.

Tried this Link on my Firefox (with addons), Firefox private and Edge, always the same result.

Happy to hear some suggestions!

There is a site that I've been accessing for months from firefox. Today, all my attempts to access it result in "Forbidden: You don't have permission to access this resource." If I bring up a safari browser, the exact same URL loads fine. I didn't change any firefox configuration settings. Any ideas?

1. I'm using containers and they are not allowing me to sign into theregister.co.uk site or any bbc.com or bbc.co.uk site if I open the site within a container.

On theregister.co.uk, clicking on log in refreshes the page but nothing else.

On the BBC sites, clicking on log in opens the same page in one or two new tabs. Oddly, if I've logged in outside of container, the Log In button flashes momentarily as Account which is what would be in the place if I were logged in.

I've tried clearing the cookies for both sites but it doesn't help. I can log into either without a problem if it's not in a container.

2. If I remove a site from a container's site list, I cannot open it in that container.

Any ideas?

Hi, I'm using Firefox 85.0.2(64-bit) Windows 10

While I'm testing local testing for website, whenever I typed/entered localhost OR localhost:8000 Firefox keep redirecting/guesing subdomain for it(which="www"). Made my testing messed up.

There's same issue on https://support.mozilla.org/en-US/questions/1216065 None of those work.

set: browser.fixup.alternate.enabled to false or Connection Settings with No proxy

Please, stop. Chrome and Edge behave normally. This site need darkmode :/

Suddenly I can no longer copy and paste to google search page. I can still search from highlighted text but That's not how I usually do it. It still works occasionally or at least once. What recently changed and how do I fix it?

It still works in chrome.

I had accidentally refreshed my Firefox, and after adding back all my old data, I found that the pocket stories were missing form my new tab. I manged to fix this issue, but when I go into new tab settings to make it show more than 3 stories, there are no options for them. It just gives me options for search, top sites, highlights, and snippets. How do I get these settings back?
