Firefox Support Forum

I can't seem to disable the certificate verification on Mozilla Firefox. As you can see on the screenshot, the error code is SEC_ERROR_UNKNOWN_ISSUER.

I tried multiple solutions, including :

- https://smallbusiness.chron.com/disable-firefox-rejecting-certificates-59249.html - The three solutions from https://stackoverflow.com/questions/20088/is-there-a-way-to-make-firefox-ignore-invalid-ssl-certificates - https://support.mozilla.org/en-US/questions/1234483 - All of the solutions from https://browserhow.com/how-to-fix-mozilla-firefox-ssl-certificate-error/ - https://itectec.com/superuser/how-to-make-firefox-ignore-all-ssl-certification-errors/

and so on.

Is there a way to disable this for only one website, or at least for all website ? I got a web interface which is self signed (if I understand everything correctly) where we can bypass the certificate "error" but it would be great if I just could configure Firefox to skip it entirely for this interface (as I'm certain it's not insecure and even if it was I'd still use it because I can't use anything else for now.

I know Chrome has a command line which do exactly what I want (--ignore-certificate-errors) but Firefox is a must go for me so I'd prefer to find an option on this browser.

Thank you for your time.

Every time I change my theme and close my browser and come back in it resets my theme. Though my theme says it is enabled. I have no idea what is causing this accept that it happens when I log in to my account. I have uninstalled my Firefox and cleaned out all registry and appdata folders for a clean install. I then re-install fresh and login to my account and BAM my theme resets every time I restart my browser. I have also closed all logins in my account.

As you can see in the image my theme is enabled but the theme is not showing. When I disable and re-enable it it will come back but when I close my browser and open it back the theme shows for about 2 seconds but reverts to this theme you see in the screenshot.

I hope this makes sense, this is very confusing.

I did a refresh (94.0.1) of Firefox. My main title bar is gone. The bar with the title File, etc. How do I get it back.

I have 3 rows now, one that shows what web site I am looking at, one that you can type in a web site, which also has a search box, one that shows often used web sites Any help would be appreciated.

Thanks, Steve

Today I ran into an issue I never experienced before and which I somehow can't fix. Whenever I hit the CTRL button (e.g. for CTRL+F, CTRL+A, CTRL+C, etc.) the zoom is decreased by 10%. Same goes when I use the CTRL button to zoom with the mouse wheel.

I'm using Firefox 94.0.1 (64-bit) under Windows 10

I tried closing the browser and opening it again, restarting the computer and using Firefox in Troubleshoot Mode, but the problem persists. A search in the forum here and on google yielded no relevant results.

Anybody who's got some good advice for me? Thank you very much.

Since the last 3 updates I have not been able to get Firefox to display peoples reviews on certain sites like Cabelas.ca. when I use other browsers there is no issue. I much prefer Firefox over chrome but I have to use Chrome in order to read any reviews on products. Is this a browser issue or during the updates did something change that I am not seeing?

Just recently, past few days, my Firefox desktop browser will not display real time quotes & trades for Binance.US. Microsoft Edge does display correctly. I then went to wife's computer and it has the same Firefox problem and the same correct display with Edge. I have deleted cookies, cache, & history to no correction. I opened Firefox in safe troubleshooting mode and the problem persists. Yahoo, Coindesk, & other sites quotes do display in real time; however, Binance.us will not in Firefox version 94.0.1.

Hi guys! Stripe.com crashes FF. The site only displays about halfway down its homepage, then crashes FF. I've cleared cookies, all history, removed and reloaded FF, turned off tracking protection for Stripe at the address bar, lowered tracking settings to standard in FF, turned off hardware acceleration, and contacted Stripe directly. But they can't help with browser specific issues accept to offer standard solutions, which I already tried. Also, Stripe works fine in Chrome.

I'm using 1password extension, and for plugins: OpenH264 Video Codec provided by Cisco Systems, Inc. and Widevine Content Decryption Module provided by Google Inc. I deactivated both those plugins but no use. Ideas? Thanks! Ken

My firefox extensions are not showing up in my toolbar. I've tried everything I've seen, turning on Private Browsing, checking the customize tab, removing Ublock Origin, but nothing has changed and they are still not there. Help!

Hi all I have scoured the articles but found no solution to this. I reinstalled Firefox on my Mac, and somehow deleted all previous profiles. I did not have 'sync' enabled, nor a FF account.

I have found a places.sqlite file on my backup external hard drive. But my current profile has an places.sqlite file already. Can I merge them??? Or can I only replace?

Dear Support,

I am using Pulse SMS in Firefox 94.01 in Windows 10, https://pulsesms.app. I receive MP4 videos via this SMS web application and Firefox will not open them, they are coming from an Apple IPHONE. I receive the following error and the video will not play.

No Video with supported format and MIME type found

I open the same Pulse SMS app in Google Chrome, MS Edge, Vivaldi and each of those applications plays back the video fine and I hear the sound. I have disabled all extensions in Firefox, and also allowed all all the Site permissions for the web app site, I have turned off enhance tracking, note of the firefox settings seem to help The MP4 will not play. Can anyone point me to a setting that might allow me to playback these videos? I have looked thru the history of Firefox and it seems to be an issue that rears it's head quite often over the years. If anyone has a solution could you please let me know. thank you for your help!

I am getting errors from online web forms that tell me I must have JavaScript enabled to continue, but when I check about:config, it shows Enable JavaScript to be True?? Is there some reason why this may happen, or do I just need to use a better browser?? Thanks in advance!!

It seems like the Language Packs aren't working in the Store Version. I switched from the normal App to the Store Version and since then I can't use another Language Pack, even if they are installed and activated as Addons. The only language correction I can use is the default US-English.

I cannot turn on the audio input and the audio output in Discord web application when running Firefox for desktop PC. The advice from Mozilla Support knowledge base regarding how to enable microphone did not help, since there is always no access request from discord.com detected in "Preferences" -> "Privacy & Security" -> "Permissions".

I am using the latest version of Firefox (94.0.1) on Windows 7 SP 1 and Windows 10 20H2. In Discord Support knowledge base the app is claimed to support Firefox version 80+.

Getting this error when browsing to https://my.xfinity.com/?cid=cust : Access Denied You don't have permission to access "http://my.xfinity.com/?" on this server.

MS edge works okay on the same laptop & same url. This is with Windows 11

I chose lavender as the background color, but I hate it. It has changed all my links to lavender and I want to go back to the default settings before I added the lavender. I want the default settings before the Colorways options were made available.

Even though I have figured out how to change the themes, the lavender color is still present in certain words. I want it to go. I want what I had before I added the lavender theme.

I have looked at the articles, but I cannot find an option that says "go back to what you had before" or "undo" or "restore default settings". I'm possibly missing a step. Don't know. I'm frustrated that I can add something so easily, but not get rid of it so easily.

Please help me restore my back ground colors to pre-Colorways add-on lavender. I have a Mac OS High Sierra 10.13.6.

Good day.

I use Firefox 94.0.1 and the latest version of CCleaner. I sometimes use the "Clear Storage Button" and "Cookie Auto Delete" addons.

My situation:

1. In Firefox, settings for clearing history, Cookie, Site settings and Cache boxes are NOT checked.

2. I do some surfing. Then I'll look in the FF "Cookies and Site Data" - Manage Data, and I see cookies.

3. *Without closing the browser*, but closing any active tabs and leaving *one* inactive tab (blank) in place.

4. I will, for instance, hit the "Clear Storage Button" - which is set up to clear cookies.

5. Looking back in the FF "Cookies and Site Data" - Manage Data, the cookies have been removed.

6. Launching CCleaner, then Options, Cookies: cookie data still shows up!!!

7. I repeat the process, same result.

8. If I then *close* FF and look again at the CCleaner, Options, Cookies, the cookies info is gone.

This is the same result with using either "Clear Storage Button" and "Cookie Auto Delete" addons.

So the situation I have is this:

- I can remove cookie data from FF using an addon.

- As long as I don't close FF completely, CCleaner will still show cookie data.

- Once I close FF completely, then cookie data in CCleaner goes away.

- Please look back at #1 above.

It seems as though an addon can delete cookies in FF, and FF shows they have been deleted, but CCleaner is still picking up some residual data from FF, or so it appears.

Sign me, "Got me boggled".

Thanks for any help.
