Firefox Support Forum

I have used and updated Firefox for years. I am now on v79. And in my prefs.js file (about:config) there is tons of old crap. Things like references to old addons which cannot even be installed any more and were removed during updates, prtiner setup stuff for printers I no longer own, and something that is causing the rendering of chase.com to be messed up and the site unusable in FF.

Is there some reasonable way to clean up the prefs.js? Using about:config does not seem to remove entries, only reset them to default. If I exit FF and edit the file in my text editor, FF doesn't work right when re-started - I have to restore the profile folder from a backup.

There must be some way. Any help/tips?

Thanks

I am trying to emulate the expected behavior I have from Chromium based browsers. I want my two email accounts to open on startup but then when I open a new window, for just the blank tab to open (Firefox home). There doesn't seem to be a way to do that. I can make them my "home" pages so that they load on startup, but then when I open a new window, it opens both of my home pages as tabs in that new window. Any help? See attached screenshot, is there something I'm missing or is this behavior just not possible in Firefox?

MBP Pro mid 2012, Firefox 79.0, High Sierra 10.13.6

I want to backup my bookmarks. When I do the following, the Library window opens but the Import and Backup button is missing. I've attached a screen shot.

1) Click Bookmarks > Show All Bookmarks from the menu bar.

2) In the Library window that opens, click the Import and Backup button in the toolbar.

I am moving to a new MBP so I need to do a backup to import my bookmarks on the new computer.

Thanks for your help

Hello and thanks in advance for any help you can give me.

For many years, I have had trouble with the rendering of https://www.chase.com/ in my Win10 Firefox install (see attached). This does NOT happen in my wife's install. I have been a user for a long, long time and this has persisted even through the update to 79.0 today. On the same machine, it renders fine in Chrome (see other attached).

As I said, the problem does not happen on my wife's computer and since it works in Chrome on the same computer I know this must be something wrong with my Firefox install. I have tried running with --safe-mode and the problem persists. I have repeatedly cleared site data/cookies and even the entire Firefox cache. The problem persists.

While I suspect there is still something hanging around in my profile that is causing this, I don't know what it is and I am loathe to erase my entire profile and start anew.

Any suggestions on how to get to the bottom of this mystery?

Thanks

Hi, I am responsible for authenticating software downloads and am looking for this information for the latest version of Firefox. Please help - SHA256, cert or other ??? would be helpful.

Hi,

It's pretty much exactly as the title says. If I copy formatted text from Google Docs that has indents and paste it elsewhere, all the indents turn into 5 spaces. All other formatting stays the same, though.

It's definitely some problem related to my browser, as I don't have the same problem on Google Chrome. I even tested it with the exact same file/text to be sure.

Any ideas?

Please help I tried many times but my websites https://10hunts.com/ doesn't load in Mozilla firefox I'm tired now

I have Windows 10, version 1903. I recently backed up my Mozilla Roaming and Local profiles to an external drive before replacing the hard drive in my laptop.

After replacing my hard drive with a new one, I restored an earlier image file of my computer in order to put back all my data onto the new drive.

Then I did a Fresh Start, effectively doing a new install of Windows 10 (v.1903).

(As far as I can tell, my old Firefox data was deleted during the Fresh Start reinstall.)

I now did a new install of Firefox onto my computer. After I opened it I synced. Because my favicons were not restored (a generic globe icon shows in their place instead), I'd like to load in my old saved profile and make that my default profile.

The problem: So I tried copying and pasting the saved profile ("bxfz7tby.default" ) back into the new Mozilla Roaming and Local profiles (e.g, into "C:\Users\,username>\AppData\Roaming\Mozilla\Firefox\Profiles\", but I can't get Firefox to access them. Instead, it only accesses the new profile it created.

I did an uninstall and tried it again, but all I ended up doing is creating another new profile. Now when I go to About:Profiles (see image), the default-release and default profiles listed don't seem to exist anymore (they aren't loadable, and they can't be found using the filepath noted there), and the actual backup profiles that I copied from my portable drive into Mozilla and that I actually see in File Explorer, doesn't show up as a profile choice.

How can I restore my old backed up profile? And if I do restore it successfully, will that also restore my missing favicons?

EVERY TIME I open Firefox I immediately get an ad asking me to download MS Edge. This occurs even when Edge is not open. 1. I have Edge downloaded but it is not my default browser – which is Firefox. 2. This ad appears even when Edge is not open. 3. I have turned off all the suggested fixes in the “Settings/Options” for both Firefox and Edge but without success. Is there any way to block these irritating pop-ups?

I have alot of open tabs on mobile phone and want to view - and then delete - each of the tabs on my desktop because it's massively slowing down my mobile. I am able to open on my desktop the synced tabs - although I can only open them either one-by-one, or the entire lot of 1,000 of them - but cannot seem to delete singular ones or a few tabs at a time when are no longer needed. Is there a way to delete a synced tab individually from a connected device that's NOT the device where the tab is currently open/ originally saved? Thanks!

I take my privacy very seriously and have disabled a large number of Firefox features which erode my privacy, including geo.enabled, dom.event.clipboardevents.enabled, dom.battery.enabled, and many more.

Today I've just found a setting I've never noticed before which makes me really nervous: geo.provider.ms-windows-location

Can anyone please tell me what this does? Is it new? Why doesn't Mozilla have a page/resource explaining what all the preferences do and how to use them?

This past week when I right click on an article on MSN.com and select the open in a new tab item the new tab appears to the right of the active tab briefly and then disappears. This happens very quickly and I have not found a way to allow the new tab to open. Any thoughts and ideas are greatly appreciated.

For a few months I have found that iI cannot download files from the internet via Firefox. I have a window 10 computer and MS Edge works. I don't like Edge though so I am loooking for a solution that will allow me to keep my good old Firefox. Currently I still use Firefox as my default browser and when I need to download files I copy the URL to Edge and download the file. Can someone help me? I am a decades long Firefox user and this has never happened before now. Thank you. David Wilds Patton

As an example, I search kijiji for kid's bicycles. It shows me the various ads but the box where the photo should be is empty. This happens with similar search results as well - words but no pictures. Have been using Firefox for many years. Why is this happening now. Using iMac with Catalina latest version.

Dear community,

I use Firefox on a Linux laptop and an Android phone.

For the past several months, I have been successfully using the Lockwise app on the Android phone to access passwords synced from my computer. I was not logged in to Firefox proper (the browser) until much more recently. Apparently, I have failed to notice that my passwords never synced to Firefox browser.

I have now reinstalled the OS on my laptop and all my passwords are gone there. They still appear in the Lockwise app, but none of my Firefox browser installs (which I all added to Firefox Sync much more recently than Lockwise) can access them. Essentially, it is as if they are only stored on my phone, anymore.

How can I get them back to the browser?

Kind regards, fNek

Hi,

On your DNS-over-HTTPS (DoH) FAQs page https://support.mozilla.org/en-US/kb/dns-over-https-doh-faqs#w_how-did-mo..., under the question "How did Mozilla choose Cloudflare as a trusted resolver?", the link to Cloudflare's privacy notice resolves in a 404. Can you please update it to point to Cloudflare's privacy notice with respect to 1.1.1.1 and Firefox?

Thanks, James

The names are often similar and the addons are sometimes not from FF.

So, how do I recover (or view) my old extensions list?

Thank you.

BTW, logins took FOREVER to load. Scary for a while.
