Firefox Support Forum

On certain websites I notices I have 'unknown errors' when trying to log in.

Usually this is remedied by either using Chrome or clearing cookies and the cache.

Both of there are inconvenient and result in a great deal of wasted time.

The usual response by these websites is "get Mozilla to fix this".

I'm getting sick of this.

I don't want to switch to Chrome but I will have to if this persists.

MacOS Monterey 12.3.1 FF 99.0.1 Have tried clearing Cache, Cookies, Troubleshoot mode.

Google Maps > Search > Share > Embed a Map, the map to be embedded is not displayed (likewise when embed is pasted into Wordpress page, for example)

While same procedure in Safari or Brave works as expected (map to be embedded is displayed in Google maps and embed code displays map in webpage using Brave or Safari).

From the Google Maps page > share > Embed a map > right click This Frame > Open in new tab And then looking in the Console. There are a few other ignored errors but then this...

Loading failed for the <script> with source “https://maps.googleapis.com/maps/api/js?client=google-maps-embed&paint_origin=&libraries=geometry,search&v=3.exp&language=en&region=us&callback=onApiLoad”.

my whatsapp web page doesnt load anymore and it just gets struck on a white screen, i have tried to delete cookies reinstall the browser but nothing happens. Im using endeavor os

Why can't I online shop with Mozilla? For months now I have had to go to another browser to use websites and make purchases. It doesn't happen 100% of the time, but enough to have me consider using a different browser permanently. I have used Firefox for years and don't want to change. But, when I need to purchase things or even pay bills and it won't let me continue on to a site, it's an issue. And yes, I have cleared cache and cookies and it doesn't seem to make a difference.

Specific examples: I logged into a store that I have purchased from before to make a new purchase. I can browse the website, but when I add to cart and try to check out, nothing. No message, not anything to help me know what the issue is. I go to Edge, pull up the site, and complete my transaction.

Today I tried to log onto a site that we just set up an account with yesterday. It's to be a guarantor on an apt for my son. We set up the acct and went today to finish the requirements and it won't let me access it. Just keeps scrolling. I go to Edge, log in with no trouble.

FF updated yesterday with the new Ubuntu 22.04 (Pop) update to 99.01. Since the update the volume control inputs are essentially disabled on all web sites, and they default to max - even when muted.

Example - youtube - all videos play full volume Reddit - even muted videos play full volume

The volume can now only be controlled by the system slider.

The same behavior does not occur in other browsers - e.g. Chromium, Opera, etc.

Can anyone assist?

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

Recently YouTube videos have stopped playing when I'm using the Firefox browser on Windows 10. This has occurred both on my laptop and on my desktop computer. The player, surrounding website, comments, description, etc. all load correctly. The video does not, instead displaying either the video's thumbnail and a buffering symbol, or a blank black screen and a buffering symbol. The time codes on the video load correctly. Ads do not play either, and instead after about 15-30 seconds of buffering the "skip ad" button appears in the lower right hand corner of the video. Videos play normally on both Chrome and Edge, and all other media content appears to load correctly (music/spotify, videos on social media websites, etc.)

So far I have tried: - Running Firefox in troubleshoot mode - Refreshing Firefox - Clearing the cache - Disabling and re-enabling hardware acceleration (didn't work either way) - Uninstalling and reinstalling Firefox - Rebooting my machine - Waiting for the problem to fix itself (it's been two weeks on my main desktop/tower and it's still not working).

At this point the only thing I haven't tried is messing with advanced config settings, and I'm avoiding that since I have no idea what any of them actually do (despite what certain reddit threads recommend).

As far as I'm aware, no specific update to either of my machines or Firefox has preceded the issue appearing. It's been going on on my desktop computer for about two weeks, the problem just started on my laptop last night.

It's worth nothing that I usually use UBlock Origin, Simple Tab Groups, and Facebook container. Those extensions are not currently installed since I had to reset my browser in the process of trying to fix the issue.

I can also confirm it's not an internet issue; speed tests show normal download/upload speeds for my wifi, and those have not varied since the issue began. All of my drivers are also currently up to date.

Background: I am on the Beta track, currently running 98.0b4 on Mac OSX 11.6.1, until kinks are worked out of Monterey.

Issue: One of the latest FF upgrades has killed my ability to login to Netflix. I get an orange popup field stating "Incorrect password. Please try again or you can reset your password." The password is fine, as I'm able to login using my backup browsers, Safari and Vivaldi. The issue persists when I try to log in using a private window that doesn't allow any add-ons, so I don't see that as the issue.

Firefox is still my preferred and default browser, so I'd like to see this resolved before.

For a long time, I often see that the apostrophe is not displayed but the code "\u2019" is there instead. It happens enough that I almost read past it as if it was correct english.

For example, a quoted Tweet on this site is shown as: "You clearly didn\u2019t bother to read her reply to him lol! " https://www.comicsands.com/aoc-clapback-musk-zuckerberg-twitter-2657252397.html

Seems to only be apostrophes. Ellipses, colons, quotations, brackets, dashes all appear fine.

I saw an article regarding Thunderbird that seemed very similar but didn't see much to help me. (questions/1312056). I saw a post about FF not using the Symbols font but that didn't help and I can't see how this should be a font issue (especially Symbol v. apostrophe).

Is there a way to fix it? The issue maybe due to the way the website is publishing quotes--I checked and found apostrophes appearing correctly on that page in the article headline and body text. The error is only inside the posted quotes.

Also, I don't see the pics of the quoted Tweets, just the text and I have to click on the date of the post to go to Twitter to see any graphic. Maybe that will help figure out what the apostrophe error is or maybe it is a second error/issue?

I run NoScript and uBlock Origin but I don' see any setting that would cause an issue. (uBlock is not blocking remote fonts. Twitter.com is not blocked by NoScript).

I'm no computer programmer or web designer but I find it hard to believe that an apostrophe should cause such a silly error.

Thank you.

I am currently using Firefox v. 100.0 (64-bit) on Windows 10 Home v. 21H2. Recently, I have been unable to get package tracking information from the website fedex.com, nor can I log into my FedEx account. When trying to track a package, the FedEx site displays the following message: "Unfortunately we are unable to retrieve your tracking results at this time. Please try again later." Likewise, when trying to log in, the site shows this message: "We are having trouble establishing a connection. Please refresh the page." Repeated attempts in both cases have failed. In the past, the fedex.com site has functioned flawlessly with Firefox. Moreover, I do not experience either of these problems with Google Chrome.

Please advise.

I cannot turn on the audio input and the audio output in Discord web application when running Firefox for desktop PC. The advice from Mozilla Support knowledge base regarding how to enable microphone did not help, since there is always no access request from discord.com detected in "Preferences" -> "Privacy & Security" -> "Permissions".

I am using the latest version of Firefox (94.0.1) on Windows 7 SP 1 and Windows 10 20H2. In Discord Support knowledge base the app is claimed to support Firefox version 80+.

Unable to log into my Citizens Bank account. I keep getting an "Access Denied" "You don't have permission to access "https:citizensbank.com/HomePage.aspx" on this server." Tried updating Firefox and Troubleshoot mode.

When viewing email on Outlook in Firefox, there now appears a rectangular black box over part of every email. This does not occur when viewing Outlook emails on Chrome or Edge. I thought it might be because of my adblocker (Ublock Origin) so I turned it off, but the black rectangle still covers part of my messages (and I have Ublock on Chrome, too, with no problem viewing Outlook).

The rectangle covers only a portion of the messages. When I scroll the message, the black rectangle remains stationary and the message scrolls behind it, thus revealing the portion previously covered by the black rectangle (a different portion of the message becomes covered).

I tried to take a screenshot to show the black rectangle covering part of the message. Amazingly, even though the black rectangle is there when I take the screenshot, the screenshot itself does not display the black rectangle....instead the message appears in the screenshot without being partially covered by the black rectangle.

Please tell me what to do to have the magazine work. It used to, but I think that some new thing like Adblock must have changed it and I cannot read the magazine now. Thanks.

Hi. In the past week, my Firefox has been giving me this message for many sites - all of which I've landed on before and I trust. Firefox wants me to contact the website owner which is not do-able. Any suggestions? Thx!

Here's the error msg I get: An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

Walmart website no longer works properly with latest Firefox 96.0.2 64-bit. It works properly with Chrome and other browsers. You can log onto the site and search for products but when you try to add a product to the cart nothing happens. You also can't actually go to the cart. Last time I used Walmart was a few weeks ago and everything worked fine!

When I try to log on to hmnow.com, all I get is a white screen. I worked with Hallmark support, but they couldn't figure it out even though I have a paid subscription with them. I've rebooted my Mac and it says I have the latest Firefox version installed. This has gone on for weeks. I've had no problem with any other website.

I download then open many student files each day. PDFs open fine automatically, but never Word files. In the Applications settings dialog, I have tried to choose the file format docx and doc. But neither are recognised as a valid file type. I realise that Microsoft is a bully and Mozilla may be trying to discourage its use, but I and the students are stuck with Word. How come docs and doc are invalid and how can I persuade Firefox to open them?

Thank you
