Instacart webpage suddenly will not display/open on Firefox but can display fine on Chrome. Instacart App on mobile phone works fine, just won't open in Firefox. Any suggestions other than using Chrome? Firefox version 101.0.1 Windows 10. Was working fine until latest update installed this morning.

I'm trying to load a temporary add-on on my browser, but when I click the button "Load temporary add-on", nothing show up.

I tried to look for errors in the console or debugging tool, but nothing. With snap, I removed with the purge option my Firefox and install it again, but the issue still appears.

Some technical details: Ubuntu 22.04 LTS Firefox version 101.0.1 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

Audio was working fine until recently. Now, firefox has no audio playing on any site.

Some sites show "PLAYING" in tab, but others like YouTube don't show that notification. Even with "PLAYING", there is no audio output.

I checked Windows settings and Firefox is set up correct (and the same as it was before it stopped working), see screenshot attached. Otherwise, I restarted Firefox, tried it in troubleshoot mode, and reinstalled Firefox. No changes.

Possible system changes include: Maybe a Firefox update occured and broke the program? I installed the game Civ5 from Steam which required some Windows VS redistributibles installed.

After upgrading to v101, Firefox no longer recognizes my Self-signed wildcard SSL for *.local.dev.

Before you tell me not to use the .dev domain, I am aware that Google owns it and we're technically not supposed to do local development with the *.local.dev domain.

I have already tried the following: 1. Set network.stricttransportsecurity.preloadlist to FALSE, and everything was working perfectly fine before v101 2. imported the server.crt into Trusted Root Authorities in Windows, and also imported it in the Certificate manager in Firefox. 3. Tried other wildcard local domains like *.test.site, *.local.ddev and these don't work either.

I even tried following recent guides to issue a new certificate with openssl and SAN, and it still doesn't work.

Screenshot of wildcard SSL attached.

hey folks,

since today firefox wont load any websites out of troubleshoot mode. not even settings/ about:config. if i open a page in a new tab it just stays blank and nothing is happening.

in troubleshoot mode i turned off hardware acceleration - nothing changed after restart. i updated the runtime file "Visual Studio 2015, 2017, 2019, and 2022", which is suggested in different help-posts, i deactivated all addons, i created a new profile and also tried an imported one from eralier today - so far nothing has worked.

i also reinstalled firefox with version 99/ version 101 two times, after i cleared %APPDATA%-data.

im also just using windows defender as antivir.

please elp, i'm out of ideas.

I know there's [[an article|https://support.mozilla.org/en-US/kb/sync-custom-preferences#w_sync-custom-preferences]] on how to sync custom preferences. I wanted to sync my toolbar customizations and some other preferences like disabling disk caching. And I don't even have other firefox instances, instead I just want to sync only on one device, so that I can continue the same setup when I signin later on the same device.

I've tried to add services.sync.prefs.sync.browser.uiCustomization.state, "services.sync.prefs.sync.browser.cache.disk.enable" and set it to true. But it doesn't work. What am I missing? No one seems to address this. May I am missing something.

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

When I try to go the the site https://tvlistings.zap2it.com/ it show top part of page while it tries to retrieve TV listings, but then the whole page goes blank. It still goes blank when in troubleshooting mode.

Works with Microsoft Edge browser. Any ideas?

Why are google sites (Youtube, Gmail and Search) getting disconnected when all other sites are still connected to the Net? This has been happening since November 2021.

When that happens I close the FF and then immediately open it. Now the google sites work properly.

Never had that problem with other sites.....never!

Why the hell is this happening? Is FF responsible or Google?

So what is the solution?

Hello Everyone,

After inserting the proxy information, webpages in the container tab refuse to load/connect, I insert the IP address and I've also tried the Fully qualified domain name, using the type://host:port syntax, I get "The proxy server is refusing connections" and "The connection has timed out" error messages.

If I setup the proxy via the settings menu the entire browser uses the proxy server address, I am trying to specify a different proxy server for each container.

Using Mac OS 12.4 and Firefox 101.0.1. After launching Firefox, a second icon appears in the "recently used" apps section of the Mac OS dock (see attached screen shot). The icon stays there and goes away, and then comes back, and then goes away, etc. This continues on and on until Firefox is closed.

Why is this happening? Never acted this way before the latest updates.

When opening pdf's attached to emails they used to automatically be opened by my pdf viewer software. Then they started opening in Firefox on another tab, which was fine. Now I first get an error message from firefox where I need to click on "open site in new window" it isn't a site but a pdf?? How do I get it to go back to opening with Adobe instead?

Thanks, Jeff

Lighter fonts (from multiple families, and on multiple websites) are rendered so poorly they are barely legible.

I already tried disabled performance settings, and turning off ClearType in Windows (it barely had any effect)

How do we fix this?

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

• My mail client is completely unaffected and is behaving normally.
• I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
• Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

Win 7 Home Premium Firefox Version 101.0.1

'Privacy & Security'->'Cookies and Site Data', 'Clear Data.'

When 'Clear Now,' Cached Web Content; is clicked, it does not zero out. (It used to clear completely).

The browser webpage has been refreshed, the browser closed and reopened, and the computer restarted but the cache does not reset.

This issue started on the morning (Pacific time) of June 26-Is this a known glitch or am I missing a detail?

Every time I run browser it messages me that downloaded file contains a virus or malware, even I deleted the file long time ago. I tried Ctrl+J "Remove from history", "Clear downloads" and Organize/Delete that entry - Nothing helps. Its deleting, but when I run Firefox its appears again and again. This bug is terrible annoying, please fix it.

In Firefox, my instructor and student grade sheet no longer displays the horizontal scroll bar to bring more data extended off to the right of the page into view. I have an image attached where the scroll bar should be present. This begin in May sometime, and I'm not sure how to fix. I have tried re-installing fresh a few times, and removed any custom settings that might have been in place. Any and all help would be VERY appreciated as one of colleagues is super frustrated and I would love to find out an answer for both him and myself.
