Firefox Community Forum

To replicate this issue, an image from my device is uploaded to a website that requires an image file input; the resulting image displayed on the website becomes corrupted and unreadable. The theory forming currently is the website is having issues retrieving or reading the input images; however, this bug seems to be consistent with several other websites, indicating Firefox is not able to read the images correctly and thus could result in fragmentation. - The image posted is a .png file of a screenshot of an attempt to post a picture to social media, based on the functionality of this bug, I am predicting this image will be fragmented and will only show blue and black lines. The image being posted online is also in a .png file format.

Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?

I used a number of extensions for years. I recently updated Firefox. Now, I don't see any of my previously installed extensions listed. What happened to them? Are they just "hiding" someplace or are they gone?

I've loved Firefox for years but can no longer use it because I have been unable to resolve this issue. All was well, an update was done, and bingo, I got this message. I don't know how to fix it. I removed Firefox from my desktop and re-installed. Same problem.

"The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem."

Hi, When connecting to a HTTP:// site, when you enter your username in the username field, Firefox prompts the user with: "This connection is not secure. Logins entered here could be compromised. Learn More".

How can I turn this message off?

We are running Firefox in kiosk mode in the browser (on a Windows 11 PC), and they are logging into an HTTP site using a touch screen, but when they click into the username box, they sometimes miss touch where to enter this username and instead touch the link mentioned in the message. This then takes them to the Mozilla homepage, but because it is running in kiosk mode, they are unable to navigate back, and they are prevented from closing and restarting Firefox. This is why we need to turn the message off.

The city that comes up on the 'weather' icon is wrong. I try to change it by following the instructions, but there is no drop down menu after I put in the correct zip code. There is no movement at all if I hit Enter or any other key. Please advise.

Every time I open eBay on Firefox I have trouble getting the items to show and some times it just freezes on the item that I am trying to buy and it slow opening pages.
