I'm a web developer working on an app running in Docker on my MacBook. Chrome, Edge and Safari trust the self-signed certificate that has been imported into the Mac's root certificate store and have no security issues, but when I try and access the web app, I'm hit with "Warning: Potential Security Risk Ahead" and the error code is MOZILLA_PKIX_ERROR_CA_CERT_USED_AS_END_ENTITY

I really miss Firefox, particularly the multi-account containers feature. What do I need to do so that Firefox will trust my certificate for my local web app?

My windows install in my dualboot pc is unable to open at the moment, I can access the windows files from my linux. But i need the firefox data on that pc that I kept. I don't remember which email I used on that account so I'm kind of stuck on getting my data from online. Is there a way to recieve all the data from another drive without opening firefox?

Just switched to firefox as my default and found that I can't sign in to netflix. It always gives me the "incorrect password" message. I've tried resetting the password, clearing cookies, restarting, turning the DNS proection off, restarting my computer, etc to no avail. Anyone else have this issue or know a potential solution?

After updating a W10 laptop from 115 to 116 of FF the user started having problems with getting to different websites (sites they worked on/with regularly). The problem is the cert DB. The doc I found says that it is cert8.db. Actually it is now cert9.DB.

What I had to do was go to task manager and kill a task that was holding the cert9.db file. Then I could rename it (cert9.old.db). Then restarted their laptop and FF came up and started fixing the cert file (as expected). This seems to have fixed their problem.

One particular website no longer works with Firefox. https://www.familysearch.org/mapp/ I had no problems with this website until a couple of weeks ago. I can use the website with no problem on other browsers. I have tried a clean re-install of Firefox and clearing cache, but still the website does not work. Any suggestions? Thanks John

2 days ago I had all my bookmarks perfectly in my browser and today when I opened firefox today, all my bookmarks were just gone without a trace, this never happened before at all, and even when I uninstalled firefox and reinstall it the bookmarks would still be there, how can I get them back?

I've been searching for a solution on HOW to edit HTML files (for websites) on my new laptop. I used to use IE11 (Internet Explorer 11), on Windows XP / 7 (32 bit), which worked spot on, the steps were as follows: (I write websites from scratch most of the time) 1) Click on, say, index.html 2) IE11 shows the actual page 3)Click on View/ Source 4)The source code shows up in Notepad 5) Edlt the code, Save and click Reload the webpage. You can straightaway see the changes.

Currently my new laptop runs Win 11 pro, Microsoft does NOT support IE11 anymore, I can however run IE11 as a add-on, BUT it does not work very well . I also tried a couple of free dedicated editing programs also, BUT they are exceedingly clumsy to use and can't equate to the old IE11 at any level. Somewhere I read that Firefox ( i have v115) can emulate what IE11 could do, hence I am on this forum posing the question, as i can't find the solution,

Anyone in the same boat?

Please share your ideas, Many thanks

I've tried all the ways mentioned to delete my search history, other than deleting each entry individually. Three particular websites just won't go. Is there some umbrella action that will delete all these references?

Hi, my problem is as follows:

I have tried to login but i don't have auth code(my google auth doesn't have firefox on it anymore) or recovery key(Windows 11 install reset my pc event tho i asked it to keep my date/files). Anyway at all to get back onto that account? I have access my emails and my login details are correct.

Having this issue with Youtube since a few days ago, on version 115.0.2 and 115.0.3, and only for videos encoded in AVC/H264. VP9 and AV1 encoded videos have no trouble buffering, only H264 is affected. Happens with or without adblocker, and on different OS. Cookies cleared, no dice.

Video would load the first 20-40 seconds, then does not buffer at all subsequently once it reaches the end of that portion. I have to skip a few seconds forward for it to load the next 20-40 secs, then it would get stuck again.

I can get around this issue by either lowering resolution to 480p (which looks terribly unwatchable), or turn VP9 streams back on (which does not work correctly on my setup, there's a driver bug that hasn't been fixed).

The sure way, and strange thing, is that AVC/H264 videos load and buffer with absolutely no issue when I'm logged out of my account. Also, works with no issue in Chromium, even while logged in.

Anyone facing this or similar issue recently too? Is it still ongoing for you?

I keep landing on this page on a loop after I have used my Gmail account to sign in. Somehow it keeps looping. I select "Continue with Gmail" and then choose my already signed-in Google account. But it takes me to the same page I started with (attached below). What am I missing here?

I am desperatly trying to play a youtube video, the on hover preview plays, but the video wont. I turned hardware acceleration of and tested in safe mode. I am using Firefox version 115.0.3 from the AUR. pls help

Every time I turn my Laptop on and visit web sites I have to reset my cookie preferences to deny - I have other add-on's such as Privacy Badger, Adblocker, Ghostery, AdBlock Plus. Do I 'need' all of these? I'm a bit paranoid about security but also a tech moron....

How do I set to block all unwanted cookies and KEEP it set?

Many thanks!!
