Running 98.02, Windows 10. Firefox keeps opening without all my tabs and other personalized information. Just a single tab or maybe 2 that have nothing to do with me. If I go to about:profiles, one of the profiles listed will (so far) have my lost information. When I recovered the first time, I quickly created a profile if the current, good configuration. However, now when the problem recurs and I go back to that profile I created, Firefox is once again a single tab of a URL I've never seen. I'm afraid I will lose everything!

BTW the first symptom was that when I clicked on a link in email (Outlook 2021), the link opened in a new Firefox window, not a new tab of the current window. This, despite telling Firefox not to do that in Settings and checking about:configuration to make sure it would not occur.

This problem appears on MacOS 10.13.3 but NOT Linux Mint 19.3 (Tricia).

Repeat-by:

1. Start here:

       https://www.cnn.com/

That page should load cleanly.

2. Now click on "Live Updates", which is the top entry in the middle column of that page, and as of 3 April 2022 11:20 AM EDT takes you to:

       https://www.cnn.com/europe/live-news/ukraine-russia-putin-news-04-3-22/index.html

On MacOS, that page loads and is momentarily visible; then the page/tab it's loaded in goes blank. On Linux, that page loads as expected and remains visible.

Notes:

The problem did not happen with Firefox 88.0.1/MacOS.

The problem does not happen with Firefox 98.0.2/Linux, i.e., it appears to be specific to MacOS.

The problem remains whether extensions are enable or disabled (one a time or all at once).

The problem remains after the cache has been flushed and pages have been reloaded.

The problem remains after Firefox has been (completely) shut down and (cleanly) restarted.

The problem does not happen with Chrome/Chromium on either MacOS or Linux.

The problem also happens on *some* other pages on CNN's site (but not all) and on *some* (but not all) pages of other sites but there doesn't seem to be a pattern that explains which URLs exhibit it and which don't. This suggests that it's not privacy settings or extensions or anything like that, because there's no reason for those to vary from page to page within any one site.

If I'm VERY fast on hitting the "X" that stops a page loading/rendering while in progress, and I get the timing just right, I can catch it before the page/tab goes blank. So it appears that Firefox is in fact fetching all the content and can render it, but then for some reason is blanking the page/tab once that's done.

The attached screenshot shows what the problematic page (from step 2 above) looks like on Linux. On MacOS it's blank, so I didn't include a screenshot of that.

I read that with version 100 on the Mac there will be some problems with some web pages like my bank can you tell me if this has been fixed or not, if not I don't want to go past version 99. Thanks for all help Michael Whitecotton

bold text' I need to stop firefox from attempting to download update 99 because it will not download it and it is taking up too much of my internet metered download time.'I have taken it off of automatically download updates,but it still pops up a message every day.

We got an alert when opening Firefox on our iMac yesterday suggesting we "refresh" and that bookmarks and saved passwords would not be affected. After the refresh, bookmarks were retained but all passwords wiped out. Further, as we painstakingly looked up or created new passwords on sites and entered them, the usual Firefox alert would come up asking if we wanted to save the new log-in, user name and password on each site, we'd select "yes" and then find none of them saved. Can anyone advise us? We're rebuilding our saved passwords on Chrome now but have had Firefox as out primary browser for over a decade.

Why why why why is FF forcing download of pdf files? It is a horrible problem for me.

Especially because I am a university prof and, in the classroom, constantly display (my own!) files from the course management system on the classroom devices. I DO NOT WANT MY FILES SAVED ONTO THE (PUBLIC) CLASSROOM DEVICE. Never mind multiple copies as it will download EACH AND EVERY TIME I open it.

I have been looking everywhere for a solution or a way to disable this feature, there seems to be no such option but I am seeing a lot of posts from people who object to this as much as I do.

After many many years of loyally using FF and a paid subscriber to some Mozilla services, I am afraid I am going to have to give up using FF is this isn't fixed NOW.

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!

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

Hi , My main machine is a personal windows laptop. Firefox sync works fine and syncs all things including "all" my installed extensions . recently company issues me a macbook and on it when i install firefox and login my account for sync it syncs other things like bookmarks but does not sync all my extensions only a few of them.

I already tried multiple things like sync delibrately from windows and then pressing sync on mac or reinstalling firefox on mac . but its the same issue.

few of the extensions that are missing :

1. Auto Tab Discard
2. Download Manager (S3)
3. DownthemAll
4. Stylus ( very important for me)
5. Tab Session Manager (THE most important for me)
6. TamperMonkey ( Important)
7. (Temporary Containers)
8. uBlock Origin
9. Xkit Rewritten
10. Zoom Image

I can't play a video when logged into a website - see https://support.mozilla.org/en-US/questions/1371380

I'm sure it is not Firefox as I have also tried Chrome and Opera; same problem. How can I debug this and find out why the video cannot be played ?

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 ?

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 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.

I want to be able to print my .docx files without saving them first. I went to General and Applications. .docx is not in the list, so I'm unable to select how it handles these files. How do I add .docx to the list of content types?

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.

Please explain: Access Denied You don't have permission to access "http://www.rei.com/user/login" on this server.

Reference #18.f697c68.1648515585.37d0ad20

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?

I'm no longer able to a particular website: https://www. bdo.com.ph onFfirefox. However, I'm still able to do so on other browsers, specifically Chrome and Edge.

The error message I receive is:
