Diễn đàn hỗ trợ Firefox

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.

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.

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?

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.

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

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”.

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.

More and more I'm having to go to other browsers like Chrome or Edge to open certain websites as they do not work through the Firefox browser. Why is this and how can i get them to work before i change browsers permanently?

When visiting sites such as the Russian Wikipedia, characters that are in the Cyrillic Times New Roman font display as blocks (shown in image). Safari does not have this problem.

Firefox 98.0.1 will not load some web pages that other browsers will. I get a message about Network Protocol Error with the option to "Try Again" which hasn't worked. I've tried many of the fixes suggested here but nothing changes. If I copy the link Firefox won't open and paste it in Brave or Opera the link loads fine. I don't want to quit Firefox but I can't spend time every day trying to fix it either.

Gmail has not been opening / responding on my desktop browser for a few days now. I cleared my cookies and cache, re-downloaded the desktop app, keep checking my privacy settings and still gmail does not respond to any commands. What should I do next?

What can I do to prevent websites from logging me out "due to inactivity" and "for your safety" (lol)? This happens with many of my financial (banking/brokerage) sites, for instance, or some tax return sites.

I went them to be like my email accounts (e.g. gmail, yahoo mail). You can have a tab open for Gmail and another tab open for yahoo mail, and even if you don't click or type a single character in hours, they will not log me out.

Is there some way to trick these patronizing "We'll log you out for your good" websites from logging me off?

I got a notification that Yandex is no longer supported and my default search engine was changed to Google?

Why does Firefox care of which search engine I use? Why I can't use Yandex? I tried to add it again but it requires to install an addon for search engines and there's no addon for Yandex search.

Ever since yesterdays (3/8/22) update I am having trouble with our wordpress page builder function. it works fine in Chrome browser, but not in firefox. can you tell me if there is a setting in the browser to update.

Since update get PR_END_OF_FILE_ERROR error on gmail; facebook.shopmy exchange; Amazon does not open right. I have tried resetting privacy setting; refresh; and nothing has worked

I am working on a project that entails saving various news stories. Since your last upgrade to 97.0.1 I have no problem with all other newspapers except for Washington Post. FF will not save them, so I am forced to click on the "progress of ongoing download" down pointing arrow and click again on the circular arrow to actually save the web page. This involves a loss of time doing a task that I should not be forced to perform. See the graphic image below to see what I'm talking about. Once I click on that circular arrow the web page will be saved as it should have to begin with. Since I normally save 30 to 40 Washington Post files every day, this adds up to a useless waste of my time. I'd appreciate it if you would look into this matter and issue a correction update so I can save Washington Post web pages without all the double stroking. Thank you.
