Diễn đàn hỗ trợ Firefox

I am unable to use my bill pay with my bank using Firefox browser. However, I am able to use it logging on with Microsoft Edge. What has changed with Firefox recently? This has only become a problem as of today.

For about the past week I've been having trouble with Gmail and Google Search in my Firefox browser. Typically, I open a Firefox window with multiple tabs and leave the window open all day. I always have Gmail and Google Calendar open in tabs. What happens is that the Gmail tab will at some point give me a message that it cannot connect and has timed out and is trying to reload, but it never reloads, it just stalls. Then I try to open a Google search bookmark to search and the tab remains blank. This happens multiple times throughout the day. Meanwhile I can open Gmail or any Google page in Chrome, which I don't like using.

Sometimes I can close out the Gmail tab that won't load and try to open Gmail in a new tab, but that stalls out too. The only way I can open Gmail again is to close out the Firefox window completely and then relaunch it, then it can open Gmail or Google... until it breaks again.

This never used to happen. I'm using the latest versions of Windows 10 and Firefox on my desktop PC. Nothing else has changed.

Please help me fix this, it's very annoying.

Hi, I get a message "No video with supported format and MIME type" when I try to watch movies on my website : https://www.spiriferminerals.com/product,25270,produkt.html The same movie works on Chrome but not on Firefox. Can you help ? Thanks ! Joanna

In Gmail, I repeatedly get "oops the system encountered a problem (#001)." Every other site works and Gmail works in other browsers. I haven't had any new add-ons or made any changes to Firefox (other than Firefox updates) in years. Does anyone know the fix?

Trying to get to the "http://localhost:631" website from my Ubuntu 22.04, but always get "can not connect". What is going on? What do I need to do to fix this? I have tried to add this website to the exception list but it changes the http to https.

I received a notice when trying to download : We can't connect to server at downloadzip.wolfgangsvault.com . It was suggested that I check that Firefox has permission to access the web ( I might be connected but behind a firewall). Please help . Thanks!

New W11 computer. checked "always ask where to save files". Restarted Firefox. It's still automatically dumping downloads in Downloads rather than asking.

Why?

Please add features so that the recently visited page during the Firefox shortcut does not apply to the shortcut list. I only want to see a fixed shortcut on the shortcut page Even the pages I recently visited have been added to the shortcut, so I have to remove them daily. It's so inconvenient.

I have used Firefox before, and I want to confirm that what i could do in the past is now no longer possible. In the screenshot, you see in the "Home" section, you are able to pick what shows for your home page and new windows. Then you see What you can choose to happen on new tabs. I have set it to pull Google's home page. You used to be able to set the new tabs to whatever you wanted as well. However, you no longer can. Is this the way it is intended to work? If so, this should be rethought. No one wants to set their browser to open a new web page whenever they want to look something up, much less just in general to get to their home page. I understand and know that you can add the home button to the toolbar, but that creates an extra step.

Now if this was intended to be this way, where may I express my dissatisfaction with this option?

On our web site we have a page that includes mp3 files, which play okay on Firefox; but on another page on the site with mp3 files, Firefox (including different versions on different computers) produces the error message, No video with supported format and MIME type found." FWIW, other browsers like Safari (Mac), Chrome (Mac and Win), and Edge (Win) all play the problematic files without a hitch.

Is there a fix for this problem that can be attempted by the non-tech types?

First of all, I have already changed my about:config browser.search.region preference to GB.

When I try to install the amazon search engine for amazon.CO.UK, via the magnifying glass on the search bar, I get this message.

Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml

Please help.

Some sites stopped opening, although in other browsers, and through the phone everything opens up. I've tried reinstalling the browser, disabling extensions, resetting DNS. It didn't help.
