Firefox 技術支援討論區

So I was cleaning out my SSD of a bunch of junk files and I think I might have deleted a file Firefox needs as when I open Firefox it seems to just blank with the search bar and when I try to go to say YouTube nothing loads. So I tried to do a fresh redownload of Firefox and the installer just this error saying "The code execution cannot proceed because vcruntime140_1.dll was not found" can someone help me get Firefox working properly again?

Hi Team,

As a concern,we want to enquire that since our company has its own product which uses Flash technology but its been known now that firefox will not suppport adobe flash player after 2020. So if we save and continue to use an oder version of firefox(with autoupdate off),will it allow to continue usage of Adobe Flash Player after 2020? Please confirm the same or any other workaround so that adobe flash player can be used within firefox after 2020 as well.

Thanks

Can I download an older version of firefox for Windows. This new 82.0 runs TERRIBLE on my computer. I have uninstalled it many times and reinstalled it and restarted it and it is not good.

Firefox is downloading all PDFs that I open rather than opening them and then downloading/saving only the ones I need to save. I've adjusted my settings to "open with Adobe Acrobat DC" and don't see any further settings. I'm on a MacBookPro. TIA!!

When downloading a file, I use to get a pop-up box that asked me if i wanted to open it or save it, and there was a box that said "don't ask me this again. I accidentally checked that box. Now every time I click on a file it asks me where I want to save it but it won't let me open it to view it first. How do get it back to the way it was?

I have tried changing my download options, I've tried re-setting the browser options. Nothing works. There has to be a way to get back to where is asks "where would you like to save" AND gives me the option to click a radial button to Open the file and view it before saving it.

Hi,

I've been using Firefox from 8 months but I never update it before. Now I want to download the latest version of firefox but, I don't know how to update the old version to new one. Do I need to delete the old version and again Install the latest version?

Please guide me about this.

Thanks.

Greetings,

I would like to get an offline installer for the latest build of Mozilla 89.0. The version i downloaded reaches back out to the site to run the setup.

As Firefox was working slowly, I used restore option as describe. But I didn't make a backup of my personnal toolbar with all my favorites... How can i restore it?

Thank you for your help
