Firefox supportforum

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

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

My sister have a facebook page with shop that I help her manage, but for some reason lately we can't access the "shop" tab of the page with firefox.

We are getting The page isn’t redirecting properly error. I cleaned cookies and cache, even tried a new private window, nothing. I tried opening in edge and everything worked like no problem.

The page is the following. https://www.facebook.com/hadrastico/shop

We experienced problems both in my workstation and my sister's laptop that also use firefox (latest version, windows 10 up to date).

Any idea? Should I fill a bug or something?

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?

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?

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

I have a website about carpet cleaners which my team has created couple of months ago, everthing was working fine but suddenly when i check the website on Mozilla Browser the images aren't loading that fast like the chrome. There is a post Best Carpet Cleaner for Pets Urine Best Carpet Cleaner for Pets Urine which has the reviews about the machine and there are lots of images including one infographics. Specifically that page wasn't loading fast in mozilla. I have to wait while scrolling to load the image!

I am stuck between two machines and can't stay on beta updates anymore because FF won't let me sync my profiles anymore.

If I can't migrate my beta channel profile to the release channel, how can I quit beta updates until the release channel catches up to me?

FF preference selected is 'download updates but let me install them' but really there is no choice. It installs and next opening of FF it is automatically installed. I already changed about:config preference for update channel to 'release' but FF merrily kept on with beta channel updates.

I need my beta channel profile customizations--varied management of permissions and add-ons and passwords on dozens of sites, customizations to stop the blinking and autoplay and movement and noise.

But: FF won't let me keep them if I go back to release.

So: how can I force FF to stop updating while the release channel catches up?

Mac/Mojave Beta channel 80.something, need to sync with release channel 79

I need to be able to be able to customize Firefox installations for all my linux desktop users. I am unable to find any current information on how to programmatically install extensions/plugins or settings for each users profile.

IMPORTANT NOTE: I already have the Check mark clicked in Settings to "open links in tabs instead of new windows" so please don't suggest that.

I tend to have a lot of tabs open (more than 100) in Firefox. Until it recently updated, no matter how many tabs I had open, if I opened a new tab, it would do so in the same window. Now, after the update, I have about 60 tabs open and anytime I open a new tab from my current window, it will after a few seconds switch to opening a new window, which is very annoying.

Does anyone have any suggestions on how to fix it?

Thank you very much for your help!

Hi Forum Folke,

Trying to make a purchase from Steam; click, click, click, get to the payment page, where I select "PayPal" as the method of payment. Get another screen that confirms proceed with PayPal; I click on "OK," and nothing happens. What's *supposed* to happen is a little popup window should open up with the PayPal login, I log in, wade through the selections, and make the payment. What *actually* happens is nothing at all. Click on "OK," and there's this "blink" and that's it. No other change to the page I'm looking at, no PayPal, no nothing... and if I persist in trying, Steam gets all uppity and tells me I've been trying to make too many purchases, try again later. Chrome handles the above scenario without any problem whatever, so the problem is not with Steam, it's with FireFox. Where should I be looking or what should I be looking for that might be preventing FireFox from doing what it should be doing? Thanks... I'm not sure what system info you need to diagnose this issue; if you'll let me know I'll be happy to dig it up and provide it.

Oh, and I'm pretty sure I can rule out my anti-virus, as again, it lets Chrome do it without problem... just not Firefox. For what that's worth....

It's so frustrating that the keyboard shortcut for closing tabs is right beside the one to quit Firefox. I've lost countless hours because of this, and it's so easy to accidentally do. Is there a way to keep this from happening? A simple "Are you sure" confirmation dialog would be great, or I really like the Chrome "hold command-Q" to exit feature. This seemingly simple function is proving extremely difficult to accomplish.

Yes, I'm aware of session restore, but (1) It does not preserve my window arrangement. I use multiple desktops for various tasks, and they each have related browser windows. (2) I need to see webpages exactly as they were when I opened them. Sessions expire, dynamic pages are refreshed, content is removed etc. That is all lost.

I do not want to disable session restore completely. It can still be useful. But, I do not want to trigger session restore automatically every time. Manual activation is ideal.

regarding: "browser.tabs.warnOnClose" I do not want a warning for closing multiple tabs. I often have many windows open and that warning gets annoying. It also doesn't prevent me from accidentally quitting when I only have one tab open.

I tried setting browser.warnOnQuit to true, but it's ignored.

I simply want a confirmation when I use the keyboard shortcut to QUIT. That's it. No side effects. Can Firefox do this?

Hello,

I'd like to make the scroll bar thinner and don't know how, all the advice I have found online either doesn't work or isn't clear enough for me to follow.

The scroll bar is ok on a new tab but becomes wider on websites and sometimes creates a horizontal scroll bar.

Thanks.

I started my computer and it told me it was slow and clicking this would correct that. Instead, it wiped out my roboform that I have used for years to log me in to my accounts. How in the hell can I get this thing corrected??????

After installing FF 79, we lost the ability to properly view material that require Java script. We verified that Java script was still enabled - it is. Chrome works perfectly on the same items. This situation created an unknowing error on our part, in that, trying to go back to 78.02, we ran into a compatibility issue with the profiles folder / files. Saving the profiles in 79 stamps them accordingly, and will not allow that folder to be used on 78.02. That unleashed 2 day's worth of struggle to get back to 78.02 with everything we had customized, plus our bookmarks. We found this compatibility issue very hard to crack using the FF help system, but eventually we succeeded by manually creating a "new folder", and copy / pasting all the files, deleting the compatibility.ini. We then invoked this default New Folder and got back to normal. And yes, Java-based items are working normally again. There seems to be no grumbling on the web (at least, as yet) about what we regard as a bug, but we did waste a couple of days on this, and are now carefully "Not now"-ing the update to 79 message, until more info is available and a fix is offered.
