Help -> About "Failed to check for updates."

This has been going on for over a week. I have downloaded and applied the installation program multiple times (>3). The problem persists. What is going on, and how do I fix it? Thanks

I downloaded a large filed in my Firefox Browser and it took me 2 days to download the file but when it's almost done, it suddenly failed download. Can you help me resume the download? I think it stopped around 60 gig.

Firefox used to give the option to open a file without saving. Now it saves everything to my downloads folder with no option to just open. (I am aware Firefox used to save the opened files in temp). This causes major clutter in my downloads folder and big disruptions to my work flow. Sometimes I just want to view the file and not save it to my working folder (downloads).

Is there a workaround to save to opened files in temp and the saved files to download?

Does Firefox give 2 different "save to" options? One option for a location to save downloaded files and one option for a location to save opened files?

Hello :) For some time now my firefox doesn't allow me to preview PDFs. If I open it, it gets downloaded at the same time which I don't need. I already tried the thing with renaming the handlers.json to handlersOLD.json but it didn't work :( does anyone know how to fix this?

I am trying to add my Android phone as a device to Firefox. I initially invoked the code scanner next to the search bar, but got a message saying that the code had to be scanned from within the Firefox app. So I installed the app and followed these instructions entitled "Connect Another Device".

• If you haven't already, install Firefox on your mobile device. • Open Firefox on your mobile device. • Open the menu, tap Settings and select Turn on Sync. • Scan this code:

There is no Turn on Sync option in the Settings menu. I have looked in every menu item that appears even remotely related to syncing with a QR code or adding a device and come up empty.

I found this exact issue in two existing questions, but neither of them had ever been answered, which makes me less than confident that mine will. If there is a Turn on Sync option in Settings, and I just overlooked it, please explain step-by-step where I can find it. If there really is no Turn on Sync option, please provide an alternate method of adding my Android phone.

Thanks.

After upgrading to v91.8.0 I experienced a multitude of issues: unwanted folders, duplicate folders, incoming mail going directly to trash, and more.

How can I do a clean install of v91.8.0, getting rid of all existing formatting and data?

Well, the subject should be self-explanatory. But i need help in creating a Firefox account. Keep in mind that I am not eligible for Google Play because I use a PC.

PLEASE help me find a way around this 'so called' improvement of auto downloading any attachment or file to my Downloads folder without any choice from me. I have checked the 'always ask' in General settings - this functionality DOES NOT WORK - IT IS A waste of time. When prompt asks what you want to do, it auto downloads IN THE BACKGROUND even if you say open and do NOT check save option. This is a MAJOR frustration, makes extra work for me to have to remember to go back to Downloads to delete all these files that just pile up, where I separately saved-off the file as usual to my other, separate intended directory. We should have the right to make that decision on whether or not we want to save it to our computers and take up space. PLEASE REVERSE THAT FUNCTIONALITY TO WHAT IS WAS BEFORE. THANK YOU>

Hello, I've only recently started using Firefox and the browser used to update automatically, however, today, I got a pop-up message asking me to update it. It was from "Mozilla Corporation", plus at that time the browser was working extremely slow, which that got me thinking that maybe it wasn't working efficiently due to not being updated. So, I ran the program and installed the update, and later, on visiting this page, I got to know that most of such pop-ups are malwares. I got extremely scared and decided to search the update history of the browser.

It said the following:

"Firefox 100.0 Installed on: (today's date) Status: The update could not be installed (patch apply failed)."

This confused me further as I don't know if what I installed was a malware program or a genuine update.

Could you please help me out ?
