Firefox Support Forum

I just tried to connect to YouTube & get "You're offline. Check your connection." I assume this is due to a DoH connection issue. I can connect in Chrome. My Firefox Mozilla Connection Settings are "Use system proxy settings", though I have set this to "No proxy" in an attempt to fix this - didn't help.

Under Privacy & Security: "Enable HTTPS-Only Mode in all windows", "Enable secure DNS using: Increased Protection" - tried "Default Protection" - no help. Using Cloudflare default.

It has been a few months since I tried YouTube - not sure what's up. It works in Firefox on my phone..

How do I stop firefox from automatically downloading files from the internet when I click on them - without even asking me if I want to download them in the first place. In "Applications", selecting "Always Ask" in "Choose how firefox handles files etc" does not work. Firefox never asks. If it cannot be disabled, I will have to stop using Firefox.

Hi all Firefoxers,

There are a few sites that I always access via a URL that could look like :

https://device.domain.com/admin/

When I went to visit that device, typing in the URL bar "device.domain..." , Firefox's 1st default suggestion shows as https://device.domain.com/

The problem is that I never visited that site, the way to access this device is https://device.domain.com/admin/ - there's no way to reconfigure the device and have an auto-redirect to .../admin location.

https://device.domain.com/ is not in my Browsing History nor do I have an open-tab. In the settings Privacy->Address Bar, disabling "Browsing History" removes https://device.domain.com/ from the suggestion list but it also removes all suggestion from the history. This is the expected behavior, the bug required fix isn't related to this.

If the "Base URL" isn't saved in the Browsing History, how can someone tell Firefox to only suggest absolute entries from the history?

WED 21FEB24 The urgent issue is that in the last few weeks, many web pages do not load content, just a grey or white screen. Some will load the header. I am the Executor for someone's estate, and I am having this trouble with some financial websites that I must access to do the job.

Its been many years since I upgraded anything. It might be that Macintosh Firefox 78.15.0 esr (64 bit) and Thunderbird 60.9.1 are the newest revs that work with OSX 10.11.6 El Capitan. I have a 2011 MacBookPro.

I don't like the changes in the user interface that Apple put into OSX after El Capitan. But I may be forced to upgrade. Too late in life to learn Linux.

Maybe the minimalist solution is to upgrade Firefox. But that may require upgrading OSX, and Apple has made it really hard to do that unless you go to the very newest. OTOH I don't know if the newer OSX will run on my 2011 MacBook Pro. If I clicked on "software update" in About This Mac, what would happen? would it just start doing it, or tell me about it first?

The last time I upgraded something, probably Thunderbird but maybe it was Firefox, I had to learn a complicated process to copy & save the User Profiles (they are in a hidden directory), and then install them into the new rev. I don't want to go through that again. I just want to run the dmg file.

There used to be a Mozilla web page with all the versions & you could download the dmg file you wanted.

If I still have problems, I would have to buy a much newer computer. A several year old MacBookPro. But I don't like the "new" disk formatting method Apple created. It saves space by not actually making copies of files, but uses a pointer to one copy. So there is a single point of failure, which makes copies pointless. I want to keep using OSX Extended (Journaled) and I would have to have the seller of the computer do that for me, before I used Migration Assistant to put my stuff on it. I also hate the welded-on hard drive; being able to pull the drive is the best "broken hardware" solution.

I don't recall if El Capitan has the "OSX Recovery" system or if that happened in a later rev.

I use SuperDuper to make a clone of my hard drive as a backup & archive. I wonder if I could connect a copy on an external drive and then startup using the external copy. Then I could upgrade Firefox and see if it works, then do the same for OSX if necessary, and Thunderbird.

Suggestions & how-to info needed. TIA

I recently sent a lot of tabs from my phone to my computer. However, when I started Firefox on my computer, since Firefox tried to load the content of all sent tabs immediately instead loading them lazily (which I think probably should be the default behavior), it took a very long time for Firefox to display even the tab that was currently selected, and I therefore decided to kill Firefox and reopen it, in the hope that all new tabs would load lazily. Instead, when I reopened Firefox, none of the new tabs where there anymore; it was as if they had never been sent. I would like to get them back, but I have no idea how to. Does anyone know if that is possible and, if so, how?

Offidocs has hijacked my Firefox browser making it impossible to read PDF files. I never added it and it does not appear in my extensions list. I've marked "always ask" in the preferences for opening PDF files but to no avail. My antivirus and Malware bytes scans are negative. How can I get rid of this?

I turned my computer on; Mozilla wanted to update, so I said yes. Then I got this:

XUL Runner Error: Platform version '120.0.1' is not compatible with minVersion>=120.0 maxVersion<=120.0

And now I have no Mozilla. Restarting the computer didn't help. How do I get the old version back? I really absolutely must have all my bookmarks back....I use them for work!

I have been using an old version of Firefox (109.0.1). I am not typically using a newer version because of an essential - to me - add-on which hasn't been updated, and which doesn't work in more recent versions.

On macOS Sierra this old version of Firefox crashes. Troubleshooting mode (I was prompted a number of times) and restarting the browser appears to eventually resolve the crash, but finally there is an issue with the memory and the browser doesn't "work."

The reason for the crash given is " MozCrashReason: Failed to load critical module "resource://gre/modules/WebNavigation.jsm" "

Sorry, posted recently and had then trouble finding out how to respond to help offered (jscher2000)! Noticed that the email version was "no-reply" so I didn't figure that would work! So, I tried to 'cut and paste' my reply (on a smartphone) and I ended up losing even the email reply text so here is a reconstruction. I tried the suggestions in order and the first one didn't have a "Restore previous session" option and the second one had "Recently closed windows" greyed out! And, when I entered "about.support" in the address bar (top rightish), I received a notice that I couldn't reach Google (Remember that I don't currently have internet access on my laptop). So, no joy there either! Can I not just change some current setting to prevent Firefox v 115.9lesr from saving the current 'Windows' and Tabs so that, when I again open Firefox, the previous session 'Windows' and Tabs would be used?!?

I have tried all fixes suggested by others reporting similar problems with previous versions, but this was noticeable for me yesterday afternoon right after some downtime and the latest version (for me) of Firefox was installed. Every time I try to use a site requiring recaptcha, the wheel spins and I get no choice to log in. I've cleared cookies and my cache, refreshed Firefox, etc. Nothing works.

For now one week, I cannot sync my browser using Firefox sync. When checking the logs, I always see :

Sync.Resource WARN GET request to https://sync-788-us-west-2.sync.services.mozilla.com/1.5/208380794/info/collections failed: [Exception... "The connection was refused" nsresult: "0x804b000d (NS_ERROR_CONNECTION_REFUSED)" location: "<unknown>" data: no] No traceback available

I have tested on multiples wifi network and mobile data and still the same error. After checking, it seem that this server is down, and I don't know were to report this.

Is this the right place to report this or is it a thing I can do to fix that ?

Thanks

My profile is not able to recover saved password. Logins.json file copied in the new profile but password not visible. In the default profile logins.json.corrupt appeared. I am looking for a procedure to recover information in corrupted profile. Can you help?

Hello there, Iam facing a problem with changing Firefox homepage background. I tried every solution, tutorial, oldposts etc. nothing seems to work, here is what I tried. -1- The chrome folder is in the right folder. -2- the naming of both CSS files userChrome, userContent. -3- enabled CSS files at startup -4- search for both CSS files in the browser toolbox for some reason I cannot find both CSS files, even though they are in the chrome directory. Also, I have 2 chrome folders one of them is located here. "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\storage\permanent\chrome" the other one I created myself which is here "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\chrome" I tried to delete the first one but I cant, I get an error that this file is being used even though I did close Firefox. What I am missing here?

I have a Firefox account in order to use the sync capabilities. After a sync between desktop and phone the desktop bookmarks are on my phone in an extra folder "desktop bookmarks" and vice versa the phone bookmarks are in folder "Mobile bookmarks" in my desktop Firefox. Is this normal behaviour? I would expect them in one common folder to have a seamless synching.

Best regards, Walter

Yesterday Firefox started closing at random, sometimes instantly as soon as I open it. The crash dialog doesn't open, and if I go to about:crashes my most recent unreported crash is from 2019. Tried refreshing, reinstalling, completely wiping all profiles and starting fresh. If I use troubleshooting mode it won't open properly at all. I am at a bit of a loss, any ideas?

Hi,

I cannot download & installed any add-ons or themes. After clicking the install button, I always get a red bar saying "Download failed. Please check your connection.". This happens on Firefox, Firefox beta and Firefox nightly.

I did some googling and found similar posts from a few years ago. These seem to suggest I don't have the correct certificate used to verify extension signatures:

• https://support.mozilla.org/en-US/questions/1257997
• https://support.mozilla.org/bm/questions/1258023

I checked my certificates and I don't have anything from "Mozilla Corporation - signingca1.addons.mozilla.org" (there's a screenshot of this cert in the first forum link above), so I think this is indeed the issue? I've attached a screenshot of my cert list where the Mozilla cert should be.

Please note I am on an M3 Pro macbook pro. It's a work laptop and I thought maybe our network settings were interfering with things, but my previous work laptop (Intel) could install add-ons just fine.

Would appreciate some help!

P.S. I found a workaround where I copied over all extension JSON and XPI files from my old laptop. So I am using my previous extensions just fine but still cannot download any new ones. Also I don't have access to my old laptop anymore so can't copy over any new ones.
