Many file types are no longer listed under Settings > Applications>Content Type at about:preferences#general. I used to be able to click on a file in an email like a Word or Excel document, and it would come up on my screen. Now Firefox asks me to Save them. I don't want to automatically save files without first looking at them. How can I get those file types in the Application list again?

I have attached a pic of the file types I have left to chose from. There used to be a lot more. How can I get back all the missing choices I have had there for years?

Hello there,

The Firefox Browser Icon that is on the taskbar requires two clicks to open the browser for the first time.

So when I single click the browser icon on the taskbar it doesn't open, so I need to click the icon again to open it. Its not that I need to double click it its just that every single time I need to click once then click it again to actually open the browser

Is there a way to fix this issue please?

Please explain why i can't read an html file with Firefox

I installed Rust on my laptop and want to browse to the documentation which is installed at file:///home/lochlann/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/rust/html/intro.html. I try to open this in Firefox and this fails with the message: Access to the file was denied

The file at /home/lochlann/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/rust/html/intro.html is not readable.

   It may have been removed, moved, or file permissions may be preventing access.

I have read permissions on the file. No matter, it fails. I try to open the file using Firefox and navigate the directory structure rather than typing in the location. The file opens in the browser, the location is listed as file:///run/user/1000/doc/1f137432/index.html. Can you explain to me why Firefox cannot render a file that is where i put it and has appropriate permissions yet can render the same file where I did not put it? I have always been a fan but this looks more like a virus than I am comfortable with.

I don't want the pdf to save to disk without my will when I open a pdf file from any website. Fire Fox saves the file first, then opens it for reading. How to change it? I want to read the pdf first and then decide what to do with it. This works similarly in Edge. FF is my main browser, I wouldn't want to change that, but I have too much garbage on my disk. every pdf is saved first, completely unnecessary.

The Send Tab/Link to Device feature only works in one direction, from iOS to MacOS. iOS to iOS never receives, although the popup says it sent. I'm using Firefox 98 on MacOS and iOS. I have a Windows 10 PC which can't receive or send tabs/links as well but I'll limit it to the Apple devices for the moment.

Sync and notifications are enabled on Laptop, iPhone, and iPad. I've de-synced and re-synced each device separately and together. I've attempted to send between each device separately and all together.

Neither iOS device can receive tabs/links from one another, nor send to each other. Laptop can receive tabs/links from both iPhone and iPad, but not send to either.

Each time I re-sync an iOS device I get a notification on the Laptop saying that "this computer is now connected with Firefox iOS". But still nothing works.

I see there is 'Remote Debugging' and 'Browser Console' under 'More Tools'. How do I use these or other tools to find out what is causing the problem please ?

Hello, I am using Firefox from like 10 years ago and it is my favorite browser all the time. I never have this problem before. However, recently after there was an update in Mozilla Firefox 100, I met some errors a few times. First, when I start the mozilla, it always say I need to update to the newest version which is I did a couple times and the error is still there when i restart the mozilla. It is same as this thread: https://support.mozilla.org/bm/questions/1264949. i already try to solve it using the solution in that thread but no successful.

Second, when I am away like 10 minutes without using the browser, it got disconnected. I cannot using it like there is no connection (my internet is always on and I tried using other browser and it is on). I need to close the mozilla and start again and it become connect again.

Thank you.

I purchased an OlnyKey to use for two factor authorization (2fa) for social media and other sites. I set it up and tried to sign in to Facebook. Immediately a drop down window opened saying Windows indicated it had to be registered with Firefox. I clicked okay and followed the steps to create a PIN which I did. Then it said to touch my Security Key which I did and another drop down box opened stating the device failed to register.

I tried this three times, now what? Why do I need to register my Security Key? How can I see if it is registered with Firefox? What is keeping it from connecting to Facebook?

Everything I read and watch does not expose this kind of problem. I don't know how to see if the problem is Firefox, Windows, or Facebook! UGH

Help!

I know Firefox recently changed some settings regarding automatic downloading of files, but I need to know how to stop Firefox from automatically downloading .pdf files that I view. Sometimes I just want to view a pdf without downloading the file. Firefox keeps automatically downloading the file, then after viewing it, I have to manually delete. I don't to do this! I just want to view the file and if I want to keep it, I'll save a copy. This is extremely annoying! Can I change the settings so that the file won't automatically save to my computer? Thanks

I have Firefox 99 for Mac "Delete cookies and site data when Firefox is closed" is unchecked History is set to "Remember History" Enhanced Tracking Protection is set to "standard"

Yet every time I return to a site where I've checked "remember me" , I'll get prompted to login, and perhaps also get a security message "you've logged in from a new computer" in my email from the site.

Is there an easy way to verify that Firefox is storing cookies for a site. Maybe an option to right-click on a site's web page and view "cookies are stored for this site" in the context menu? I'm losing a lot of my productivity time logging back into sites that I just logged into earlier in the day.

HI! I'm using Firefox 98 on Linux Ubuntu 20.04. after the last update I found several settings changed and I had to reset them, but there is one setting I can't manage. In the download preferences I set all the Microsoft Excel entries to "Always ask", but every time that I try to see an Excel file (no download, just open with ...), this is automatically downloaded. I definitively don't want to download it. How can I change this behavior? P.S.: I realized right now that there is the same problem with .docx files and I don't know how many others file types.

Before version 98 of Firefox, it would remember where I downloaded files to based on what site I'm downloading the file from. For example: when I would download a statement PDF from American Express, the Firefox download prompt would automatically be navigated to <...documents\records\AmEx\statements>. Then, when I would go to download something like the latest Firefox installer, the download prompt would automatically start in the folder <...programs\standard programs\Firefox>. No navigation needed in either case. Now, with version 98, all Firefox can remember is the last place I downloaded to, with no memory of site context. (This includes sites I've been to more than once since the update to version 98.)

This was a very convenient, time-saving feature. Is there any way to restore this site-contextual memory of download directories?

(I tried searching through existing questions, but my apologies if I missed an existing question on this topic.)

Thank you!
