Firefox Support Forum

Recently my browser will open a Settings tab whenever I click on an autofill dropdown selection. Any autofill selection from username/passwords to simple Name/phonenumber/etc autofills. It's very annoying and I can figure out why it's doing it. How do I make it stop? I'm running Firefox 126.0.1 (64-bit) on a Windows PC.

Why do I need a new profile every single little update? How can I get my saved session, bookmarks, history, open tabs, extensions and preferences from my old profile? Manually copying files from the old profile is not a solution - it's a workaround and not a great one. Lots of things get left behind. Alternatively: what file in my "old" profile do I need to manipulate to trick Firefox into using it with the new version?

My system repeated asks if I want Firefox to be my default browser. Equally as many times I have indicated yes but why doesn't it stick? Running Win10 latest update. Please help me get rid of this annoyance.

Hello, I have a very weak internet connection and I've been experimenting with ways to lessen the burden of the slow connection by increasing the time that the cache from websites can stay on my computer (I've already increased browser.cache.disk.capacity and set browser.cache.check_doc_frequency to 2, but the files still end up expiring eventually forcing them to be re-downloaded even though I know these cache files never change).

So far I've had some success with this extension (https://addons.mozilla.org/en-US/firefox/addon/cache-longer/) it definitely works but very inconsistently so I've tried to directly edit the cache files found in Profiles\someprofile.default-release\cache2\entries but every time I edit the max-age on the cache-control line or any other line firefox just erases the cache file completely then re-downloads it.

TL;DR - Is there someway of getting firefox to ignore the cache file expiry dates and cache-control age or at least editing these files to extend their life?

I appreciate any help in this!

i'm missing some of the default search engines in the bar ebay and amazon. i hit the button "restore default search engines" in setting to try and fix it no luck. only give me back wikipedia, bing, duckduckgo but not amazon and ebay two sites i visit a lot.

this been happening to me for the past year and every time i had to go in the c drive and delete the mozilla folders and reinstall firefox to get them back. then use it after a month or two later they disappeared for no reason. this only happens on my desktop and not my laptop how do i make this stop happening?

Every day on the second or third tab the website will not load. If I open firefox again the site will load immediately. These can be bookmarked sites previously used one million times or linked sites embedded in a current tab. Your support pages have not helped. I'm about to ditch Firefox MS Edge!

I am on a mailing list from the Smithsonian Magazine. I receive a daily email containing links to interesting stories. The links work and take me to the correct page, however, I am unable to scroll the page up to read the article. They used to scroll, but not now when I go there by clicking a link in the email. The email also contains a link named View in Browser, and the email appears in Firefox and I can scroll the email, but if I click on a link in that email displayed in the browser, the page still will not scroll up. Problem not present in Chrome or Edge. I previously reported this to Mozilla in Feedback and to the Smithsonian about 2 weeks ago, but still no change in his strange behavior. Firefox 126.0.1 (64 bit)

Hello everyone! I am having a pretty strange issue with my [website ], it shows an SSL certificate on all the other browsers, but, on Mozilla Firefox, it shows not secure issue, which is quite pressing. Can anybody tell me what's wrong here?

I used CCleaner this morning to scan and clean up my computer. (I did it over the weekend as well and it didn't affect my Firefox). Now I can't even open Firefox. the icon on my windows taskbar is gone as well. I tried to uninstall and then reinstall Firefox, but that didn't work. I also tried to "refresh" Firefox (or whatever it is called that is recommended when trying to uninstall).

Please help. I really need my Firefox to work!

Thank you, Jeri

For some reason the developer tool on Firefox is just completely blank when I open it. Nothing will load and I can't even close out of it. Any ideas on how to fix this?

On firefox 126.0 (64-bit) the option for spelling check is enabled, but will not appear on the context menu box when right clicked. This happens for the desktop sites of Facebook and Instagram.

We are receiving the following error when we change the security.OCSP.enabled to "1" and security.OCSP.require to "true":

(Invalid OCSP signing certificate in OCSP response(Error code: sec_error_ocsp_invalid_signing_cert)

We are in an airgapped environment and have our own OCSP responder we are attempting to get Firefox to work with. What configuration does Firefox need in order to solve this error?

I'm unable to load this specific website "https://doy2mn9upadnk.cloudfront.net/" just on Firefox browser, i keep getting same error "PR_CONNECT_RESET_ERROR" yet it loads perfectly fine in Chrome. I don't use any vpn/proxy

Hello Mozilla community,

I'm encountering a perplexing issue with Mozilla Firefox that I hope someone here can shed some light on. Whenever I set Mozilla Firefox as my default browser, I experience difficulties accessing my website. The site continuously buffers but never fully loads, leaving me unable to view its content.

However, when I switch to a different browser as my default, such as Google Chrome or Microsoft Edge, the website loads without any issues moreover my website is related to Picoworker which runs smoothly on other browsers (Screenshot is also attached). This leads me to believe that the problem might be specific to Mozilla Firefox.

I've tried troubleshooting by clearing the browser cache, disabling extensions, and even reinstalling Firefox, but the problem persists. I've also checked for any errors in the browser console, but nothing seems out of the ordinary.

Could there be any compatibility issues between my website and Mozilla Firefox that are causing this problem? Or is there something else I should investigate to resolve this issue?

Any insights or suggestions would be greatly appreciated. Thank you in advance for your assistance!

Whenever I try to log into my online banking all I get is a white screen, nothing whatsoever.

I can log in just fine using the dreaded Microsoft Edge or Chrome but firefox will not work.

Now, I do know that I have actually logged in with firefox because if I come back to the page 10 minute later I get a banking message saying that as I haven't done anything for 10 minutes it has now logged me out!

I have cleared cache & cookies, I've started in safe mode and looked at the threads in the forum but nothing helps.

This is happening on all instances of firefox that I have, work, home, laptop.

please help

thanks

Directions are sync & save data. This is wrong. There is NO "sync and save data" in the iOS FF menu. See attached. Therefore cannot scan QR code. Email does not work because FF does not recognize my password which is written down and I am signed on to Mozilla. in iPhone settings FF allows camera. FF is set up to permit sync. The open tabs on PC do not sync to FF on phone. All directions do not work or are totally unclear. Nothing seems to agree with anything. Cannot sync. Cannot scan QR code. Cannot verify password.
