Firefox Support Forum

I installed a dev version of Firefox to test a plugin.

Then I uninstalled the dev version, but now none of my profiles on the regular version work...

Please help me, I really need my old browser history and cookies.

When I try to use one of my old profiles, I get "You've launched an older version of Firefox" and it tells me to either Create New Profile or Exit.

I read online that people add "-allow-downgrade" to the Windows shortcut, but this does nothing for me.

Thanks you and please help!

I have been using sandrawhitfield@comcast.net as user name for Firefox account. I want to delete that email because I'm leaving comcast ASAP. I read instruction that say add a new email name as a secondary account and then delete the primary one above. I entered whitfieldsandra@gmail.com. I got a message that said that account already exists. Since I didn't know that or remember any password for it, I entered whitfieldsandra@gmail.com and said "forgot password." I changed it Now Firefox won't let me in using the whitfieldsandra@gmail.com account. Would appreciate any help you can offer.

I installed Firefox years ago. This morning, when I click on the browser icon, I get this message: Error platform '127.0.2' is not compatible with minVersion>= 127.0.1 maxVersion<= 127.0.1

What is going on? The browser updates itself so I don't do anything. But now, it doesn't work. I use an alternate browser to send this message to you.

Since my last upgrade my You Tube starts up in the tiny right hand screen, fails to go to full screen or just disappear unless I close Firefox and restart often multiple times. This only happens on Firefox and only since the last upgrade.

Firefox is my favourite browser so I prefer using it in all my online activities. When I go to Adobe Firefly though, I consistently get a warning that this browser is not compatible and they suggest using Chrome, Safari or the latest version of Firefox !!! I am using the latest version available, 127.0.2 but Adobe does not detect it correctly. I have to switch to Chrome, that I'm not very fond of. I saw that a similar issue was posted 10 months ago but it's now archived and I can't even include a link to it here :( So, I hope this comment helps in case others have the same problem. I also hope Mozilla can fix the bug or whatever gets in the way. Lenovo laptop - Windows 10 updated Thanks!

Hello, when in the library, pressing F6 is meant to "Focus Search Field". This is documented at https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly

However, since a recent update this no longer works. Instead, pressing F6 now switches the keyboard focus to the lefthand tree pane. A further press of shift+tab is needed to move to the search box.

My questions are: Has F6 stopped jumping to the library search box for anyone else? If so, was this a deliberate design choice? Does anyone know of an alternate keyboard shortcut to jump to the searchbox? Finally, is there anyway to revert to the old F6 behaviour?

Even if you can only answer the first question that would help, so I can determine whether or not it is just my Firefox. Although I have already tested in a brand new profile with the same results.

Thanks.

I'm sort of fed news that are often "Pro-women" by pocket in the name of thought-provoking stories. I feel that this has to do with some brain-washing agenda. I don't want to see these stupid pro-women news slapped on my face every time I open Firefox. How to show "pro-human" news that include both pro-men news and pro-women news?

Right now, I'm seeing many "Feminist news" rather than anti-feminist news. So, I'm completely blinded by one side of the coin. Here's the problem. Even when I see these feminist news, it's always positive about them. There are no "Redpill, MGTOW, MRA, MRM" news which is obviously the other side of the coin and I do see it, it's often negative. I see a bias here. I don't want that bias to be fed to my brain.

In short, I want to see a balanced view or "Pro-male" news because I'm a man. I don't want to be fed all these "Pro-female" news to me.

I have noticed in the help section that all sync data is removed if password is reset. I have just lost all my passwords, bookmarks, settings, everything, because I had to format my computer and didn't memorize my firefox password.

Is there any chance at all to have my data restored regardless? I understand I am at fault, but this outreach is my last hope, I guess.

YouTube has been so slow in Firefox. It just takes a ton of time for the video to actually play. It's just a spinning circle in a video. I can refresh several times and then it plays. I cleared my cache, history, data...etc everything from Firefox. That seemed to help for a bit. Then it just resulted back to being slow. It's just in Firefox. I played videos in Edge. It was fine. No issues. It's just FireFox. It started most recently too. It wasn't happening a week ago. I even tried going back to an old version of Firefox. Didn't help. Anyone know how to fix? Not using ad blockers either FYI. I just want videos to play normally and fast.

When I logged onto Firefox this morning it asked me to update which I did. When I got onto Firefox all my tabs were gone. Please tell me if I did something to cause this and how to keep this from happening again. I do have it set up to restore tabs when logged off and starting up again. Also please tell me how to get my tabs back! I tried to follow instructions for this but actually didn't have the things they said to click on. Thanks so much for your help!!

I recently installed Firefox and I keep getting crash notices, even when it is not open/running...

I have verified this through the task manager...Nothing named Firefox or Mozilla is running...

I don't have this issue with either Brave or Chrome, and I have, and keep updated ESET software, so I KNOW this is a Firefox issue...

Unless this issue can be corrected, I will have no choice but to uninstall it, as I don't need software that crashes even when it is not being used...

So i'm a basic PC user and not a Pro to solve Problems related to Web browsers. İ wonder if this happens to any one out there using Latest version of Firefox. (127.0.2 64bit) PS:İ use a app called user agent switcher to fix freezing or lagging or buffering. İ have read some where on the internet that youtube is doing it on purpose?. This happens only with Firefox but not with Microsoft edge.

Recently Roboform add-on has not been working with Firefox I have made several efforts to ensure that it works automatically filling in passwords as previously but the add-on does not seem stable, afte reloading it works briefly then stops again. Has anyone had this problem and found a resolution? Thanks

How do I disable secure connections for local domains? like http://nas.local or http://nas.home.arpa ?

I search for the subject but nothing came up. Apologies if this has been asked before.

Hi.

I have several internal sites, each signed with their own internal CA/subCA. These CAs are all named the same, but have different crypto materials.

If I import just 1 CA into FF (directly or in Windows store with security.enterprise_roots.enabled ), the site with that CA works fine (browser warning is not presented), but ALL those other internal sites give this error:

An error occurred during a connection to 10.1.1.1. Peer’s certificate has an invalid signature. Error code: SEC_ERROR_BAD_SIGNATURE

with no option to add a security exception.

If I add the CA for another site, that one works as well, the others won't. If I remove all the internal CAs, all the sites start working again (with browser warning, ofc.).

I tried in Chrome and Edge and I get the option to create a security exception for the sites for which I did not install their CA, which looks like the ideal/preferrable option to me.

Is this as intended (and why?) or can it be fixed?

This looks somewhat similar to this: https://support.mozilla.org/questions/1170738

Thank you. Davide.

A while back, I had some very bad cataracts. In order to view text more easily, I somehow managed to change black text against a white background to white text against a black background in the pdf reader's settings. A side effect of this change was that color became grayscale. I would now like to return the settings to default. I've lost the article on how I made the changes. How can I get the pdf reader back to it's default settings?

I've tried uninstalling and reinstalling Firefox. The settings did not change.

Help!

I found that my session activity on a secure (logged-in) website was being interfered with. I could not log-out of that website. After I closed Firefox, a notice appeared that an update was in progress. Why should a Firefox update interfere with an active session? Is this an updating issue that needs fixing?
