Fóram Tacaíochta Firefox

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.

I used a siteblocker and i tried blocking about:addons, wouldn't allow it so someone tell me how. im literally trying to prevent myself from removing extension i literally jumped from one browser to another just to make this shit possible please.

I'm using 64-bit Linux Mint 20.3 LTS, and the latest version of Firefox from the repositories (101). Suddenly, for no reason I know, my default profile has started crashing immediately on trying to run Firefox. A small window comes up with the error message

XML Parsing Error: not well-formed Location: chrome://browser/content/browser.xhtml

     <button when-cofnection}"secure-cert-user-overridden"="" <="" pre="">
and then a line of ------^  where the ^ indicates between the t and the i of cofnection
Yes, I emphasise that I HAVE copied the error message carefully, including the mismatched bracket pair and the cofnection rather than (I assume) connection
I've managed to get a working version of Firefox by creating a new profile and using that (as in for posting this request for help), and I do have a recent backup of my bookmarks, but it will be a royal PITA if all my logins and passwords have disappeared. I don't want to go any further than this without some guidance, as all the messages I've found detailing how to fix this seem to make the assumption that I'm running Windows. 
Can anybody help, please?

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.

Hello,

Since 2 days ago, I've been unable to stream Amazon prime videos via Firefox. I'd get the error "Video unavailable. For assistance, please go to amazon help".

Amazon prime videos stream fine in Chrome Amazon prime app on my Android phone also works fine.

I have tried everything on the amazon help page (unless they don't apply), still won't work.

(List of their tips:

   * Close the Prime Video app on your device (or your web browser, if you're watching on your computer).
   * Restart your computer or connected device.
   * Ensure that your device or web browser has the latest updates.
   * Ensure that you’re not using the same account on multiple devices - you can only stream the same title to two devices at a time.
   * Ensure that any external device is connected to your TV or display using an HDMI cable that is compatible with HDCP 1.4 (for HD content) or HDCP 2.2 (for UHD and/or HDR content).
   * Pause other Internet activity – especially if other devices are using the network at the same time.
   * Check your Internet connection. You may need to restart your connected device and/or router.
   * If you’re able to connect to the Internet on other devices, update your connect device’s DNS settings. Please check with your device’s manufacturer for further details.
   * If you’re attempting to control a device using Alexa, try to unpair then pair the device again in the Alexa app.
   * Deactivate any VPN or proxy servers. )

Similar issue with Audible. Cannot play anything via Firefox. It's just frozen. Audible app on my phone works fine.

Thanks for your time

How can I set my location in Firefox. I know better than anyone on the web where I am located, and Firefox is locating me hundreds of miles away, so I just want to set the Zip code for my actual location. Thanks for any advice! -Harry

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?

How do I enable Javascript on Firefox Android? There are many so-called solutions on the net, but the one with "about-config" does not work; it just starts a search. According to mozilla it does not work on mobile devices anyway. So, does anyone really know? Cheers

Hello, I experience a XUL Runner error message after attempting to update Firefox and in following the guidance to rectify the error deleted the Firefox folder including the bookmarks. Is there anyway of recovering the bookmarks (maybe with a third party program) or are they lost forever? Thank you.

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?

Lauching Firefox browser onto desktop after starting is VERY slow. No other browser is slow to start. No suggestion about "fix slowness" in Firefox HELP is apparent. How to fix slow launching?

Unable to complete backup of firefox profile because of over-length file names in storage sub-directory. Is is ok to simply delete one or more file names which are old URL's and no longer required? Clear History All doesn't clean them out. (Firefox 101.0.1 (64-bit) on WIndows 10) thanks

Hi,

I'm looking for a plugin or website that is able to convert voice to text capability on Firefox. For Chrome there are many solutions (VoiceNote II, Voice Recognition, Dictanote). And I need to use it on firefox.

In firefox, as I think, permissions settings/UI haven't yet been sorted out however, so permission can't be granted to use it by the user, so it can't be used.

Thank you!

When I ask WordPress to "preview in new tab," I get a File Not Found screen. (See uploaded image.) This works fine in Chrome (which I rarely use) but not in Firefox, so I'm thinking it might be a Firefox issue. The Tablet and Mobile previews work fine, but they don't require a new tab. I thought it might have to do with pop-ups, so I made my blog's URL an exception. That didn't help. Then I disabled the pop-up blocker altogether. That didn't help either. I've never had this problem before although I've been using both Firefox and WordPress for many years. I'm working on an old laptop (current one is kaput), but I think everything's up to date. Windows 10. Any idea what the problem might be? TIA for any help. This is driving me nuts!

When I change the brightness of my computer while Firefox is open, the changes are not saved when I close Firefox. For example, if I lower my brightness from 100 to 80 while Firefox is open, once I close Firefox, the brightness of my screen increases back to 100 after a few seconds. Similarly, when I reopen Firefox, my brightness drops from 100 to 80 as that was the setting the brightness was set at when Firefox was closed. This does not happen with any other program, especially other browsers, that I have on my computer. Do any of you experience or know of this problem and do you have any advice on how to fix the issue?

(I have tried booting Firefox in Troubleshooting Mode, refreshing Firefox and reinstalling Firefox. My computer is also up to date on the latest Windows updates. This issue was not always present with Firefox and only began recently, within the last two weeks.)

Please see https://support.mozilla.org/en-US/questions/1311330 That solution does not work for me. Mac Pro with M1 chip running 12.4 Thanks!
