Since about 2 weeks ago many AOL attachments are not opening (pdf.s are but others eg Word not). I have read thru' previous messages on this (in 2021) but turning off enhanced tracking has not fixed it. My attachments open in Edge and Chrome. Like others I would like to stay with Firefox but cannot live with this problem. Help please

We have a AJAX uploader (Cutewebui) in our site. It was working fine for smaller and larger files. But after upgrading firefox version to 100, it is not working. It is giving error 'html5: the upload task is interrupted'.

For older versions it is working fine.

Please help us to resolve it.

We have a normal file upload control in our website. It was working fine for smaller and larger files. But after upgrading firefox version to 100, it is not working. If file size is less than 250 kb then it works sometimes.

For older Firefox versions and other web browsers (Chrome, Edge) it is still working fine.

No error coming at UI/web console:

i opened firefox (v.95) and tried opening up my email and found that all my saved passwords were gone from firefox on my computer. it said i should crate a firefox account to get my logins back so i did and i still could not access any of my web logins. so i searched the help pages. opened up my profile n made a backup of my key3, key4, n loginjson files, downloaded v.91 firefox esr and copied my key3 file into a new profile.

so i still dont have my web logins ... n now i have an outdated version of firefox with none of my bookmarks either. im sick of troubleshooting n my wifi is almost out for the month.

how do i get my web logins and bookmarks back so i dont have to spend hundreds of hours recreating them?

Is it possible to use the keyboard only to adjust the width of the browser window? In other words, is there an alternative to clicking and dragging the mouse to change the browser size?

Thanks for your help!

I am using a new iMac with the latest version of Firefox (100.0.2) Lately when I am reading articles on news sites such as CNN or The Guardian, or on Twitter, when I click on the video the screen goes black and stays black. No video or audio. This is incredibly frustrating. Also, even when I was able to watch videos, the default was that the sound was off. I would like to know how to fix both these issues ASAP!! Thank you

As of this morning, the Firefox browser on my work computer does not get access to any website - including mozilla itself. On the same computer Safari works without problems, on my smartphone and in the same wifi network my mobile Firefox works.

What is wrong?

Hi,

I had to reset my computer.

I had Firefox sync on it and in the past all I’ve had to do is login and it restores history bookmarks and setting when I install it on a new or reset device

It’s not doing it this time, any advice?

Hi there! Well, another company told my business partner that their product does not like Firefox so we should use Chrome and maybe Edge. First, that is a crock, but seems to be a standard answer from anyone in the business world, sadly. I would not trust Edge or Chrome, especially those two, if they were the last platforms on earth. So, help pretty please?

Is there a setting that we can use that will assist in using RSMeans Online Version so it will work more effectively? Whenever we get an error message or it just won't open, they blame it on Firefox.

Is it possible to revoke 'tabs' permission from an addon that grants it by default?

I modified the script provided here (https://support.mozilla.org/en-US/questions/1257097), I got a successful message but permission is still there.

browser.permissions.getAll().then(resp => {

 if (resp.permissions.length == 0){
   console.log('There are no permissions for this extension');
 } else {
   if (resp.permissions.includes('tabs')){
     console.log('Attempting to remove "tabs" permission --');
     browser.permissions.remove({permissions: ["tabs"]}).then(msg => {
       console.log('Removal successful (' + msg + ')');}).catch(err => {
       console.log('Problem: ' + err)});
   } else {
     console.log('Did not find the "tabs" permission, but found these: [' + resp.permissions.join(',') + ']');
   }
 }

});

thanks

After factory resetting my laptop, all my bookmarks are gone. When I try to the *restore bookmarks*, the only date available to select is after the reset. Any help?

Every day I am interrupted by McAfee with daily notifications across my screen saying they have detected a virus and to sign up with them. I have NEVER been a customer of McAfee and would like these nuisances to stop. Is there a way I can ban them from my pc. Thank you.

I'm on Ubuntu 22.04 which is using the snap package of Firefox.

It seems that I cannot open local files in the /tmp directory. When I place a test.html file there and run `firefox /tmp/test.html`, it returns a file not found error. Why?

I don't have the problem with files in my home directory.

Good day

Even though my settings is set for "always ask ..", in the latest Firefox versions all files are automatically saved to "Downloads" on my hard drive. Could you please rectify this error?

Regards

George
