I cannot use the PDF Viewer on Firefox 91.5.0esr (64-bit). Instead, I get an incessant popup asking what to do with the file. I've tried:

1. Selecting `Firefox` as the program to open the PDF. A new tab opens along with the popup.
2. Selecting `Firefox.exe`. Same deal
3. Modifying Preferences -> Applications -> "Portable Desktop Format ... (app or binary)" to Firefox. It won't let me - I can choose anything else or any other program, but choosing "Firefox" won't stick
4. Opening Firefox in "Troubleshoot Mode" (Help -> Troubleshoot Mode) then attempting all of the above. The setting still doesn't stick.
5. Disabling Hardware Acceleration, as one person cited that.

Every other thread has either cited changing the setting for PDF's to "Open in Firefox" or various names. Fear not, I've tried that, and am still at an impass. Any help beyond that is appreciated :)

I have Firefox 91.6.0esr (64-bit) on Windows. Previously I could access PDFs on a number of websites using the inbuilt PDF viewer. However now Firefox returns a save-as prompt.

I have checked the headers of some of these pdf pages and the header content-disposition: inline; filename=<abcdefg> is contained which I think should cause the PDF to be rendered in the browser but this is not happening. The pdfs on the same pages can be viewed using Edge.

Has the behavior of Firefox recently been changed?

When logging into my financial institutions website it reports back that I have version 91... of the Firefox browser installed and that it isn't supported. I actually have version 101.0.1 as reported by the browser itself. I called them and they asked me to check my version of Firefox by using www.whatismybrowser.com and it reports back that I'm running version 91. Can you help?

I would like Firefox to access the Mac OS "Dictionary" for immediate definitions, the way it accesses its own dictionary for spelling, or as Mac's Safari, accesses the Mac dictionary. I see nothing listed in Firefox>Services, nor does the OS's Services Preferences show Firefox as an app to connect services to. I can always get the definition with a right-click on the highlighted word, but I'd like the definition to be a readily available as the spelling.

TIA,

Hi. I've noticed in the last few months that my Mac Book Air overheats badly after just 20 mins watching Netflix. I've had it checked and the insides are clean and the fan is fine. Thanks.

It's still outputing, I can paste it out but the output font got glitched

Hello

Google has a service called "Takeout" through which users can download all of Chrome's synchronized data, including history and bookmarks, in a zip file.

Does Mozilla have such a service for Firefox sync?

Can websites i visit track my browsertheme for example system default or light or dark theme? I like the dark theme but i'm not using it because i fear it makes my browser much more unique, is that so? If so, is there a preference or another way to prefent websites from tracking my browser theme?

Hello, I have a strange issue. When I am in Gmail using Firefox, my time is off by 5 hours. I can open Gmail in Edge and the time is correct.

I have 2 time zones listed in my Google calendar. I removed the secondary one and the time still stays the same.

One posted mentioned that they changed the computer time zone and this resolved the issue. I tried that and still get the same incorrect time.

I can log into my laptop and I get the same issue with Firefox being 5 hours off but Edge being right on time.

Any input would be greatly appreciated. Thanks Mike

Just paid $150.00 for a remote session from my computer store. Advice is: My older computer (2004)and it's graphic capabilities aren't compatible with newest FF. So I'll stick with older version (9) until I decide to get new computer. Firefox is my preference, but if I update, it's likely to break again. Please tell me how to stop all update notices. It is maddening. Or, if you can do it, please do. I don't want to use the others. It has crashed twice, just FF, in the last few days. A system restore saved me, but I updated and lost it. Can you help this not wealthy person? I thank you for your fine product, and your help.

Anyone know if there is a way to import Google Chrome extensions into Firefox. I am moving over and want to make it easy. When I search all I get is bookmarks which I know how to do.

TIA!

We are seeing sec_error_bad_der error when trying to open a link with service certificate generated with x509.SHA256WithRSA signature algorithm. My question is, does FF support SHA256WithRSA?

Hi, when I use Firefox on this machine, the bookmark sync doesn't work as expected. Instead of maintaining the order of the other devices' bookmark toolbar, it is ordering the non-folder bookmarks before the foldered bookmarks. How can I make it so the bookmark toolbar is the same across all devices? I have tried deleted places.sqlite and backupbookmarks folder.

Thank you!

I am getting the "Did Not Connect: Potential Security Issue" error on websites that are clearly not security threats. Examples are twitch.tv, youtube.com, gmail.com and since I use duckduckgo, I cant even search something because it redirects me to the website duckduckgo.com/(whatever i searched), which also creates the error. I don't believe it is a network error because it allows me to visit all of these websites when I am using the chrome browser. Sometimes when I get the error, it has the yellow border around the screen so I can click on advanced options and click "go to the website anyways", and sometimes that option is not there. Also, the error will happen on and off for some websites. For example, yesterday I wasn't able to access gmail.com because the glitch was happening on it, but today I am able to visit the site just fine.

For example when i download Tor they share a PGP KEY to verify the integrity of the downloaded exe. Other websites share for exmaple sha 1 or sha256 or md5.

However i cannot find any such option for firefox browser. Am i blind or it doesn't exist? Then how am i supposed to be 100% sure that my downloaded exe has not been modified by someone like my ISP, Government, Criminals/Hackers?

Firefox currently has a URL color formatting scheme which greys-out all parts of the URL in the address bar except for the top-level domain and the 2nd-level domain (with some exceptions).

I am building a website where my organization-specific domain is NOT located on the 2nd-level domain, but rather on the 3rd-level domain.

I plan to use the domain "obb.ll.land". The "ll.land" part is basically a domain that the Liberland Government operates and from which it sells 3rd-level domains to members of the public. Think of "ll.land" as a temporary ccTLD for Liberland. (ICANN requires countries to be on the ISO-3166 list—which Liberland is not yet on—in order to register an official Internet ccTLD.) Therefore, any domain that is formatted as "[SUBDOMAIN].ll.land" should be presumed to be the foundational domain for a given organization that uses it.

Therefore, when a client sees a Liberlandic website, the domain should have the 3rd-level domain included in the black-text portion of Firefox's URL color formatting scheme. Otherwise the scheme would be misleading about the true nature of the website involved. For example, the 3rd-level domain of "https://www.floating.ll.land/" should be included in the black-text portion. Same with the 3rd-level domain of "https://register.ll.land/". However, as of this writing, no ".ll.land" site has the appropriate URL coloration to my knowledge.

How can I solve this problem? Is there something which developers like me should add to our websites individually, or will Mozilla be responsible for handling this matter?

Thank you all in advance! :)

There is a known issue for some i3 users that when we click the right-mouse button, the context menu will pop up in a position where the first item in the menu is already highlighted, so when the right mouse button is released, it automatically "selects" that item. So if we want to copy a link, for example, we have to be careful to move the mouse before releasing the button or that link will immediately be opened in a new tab.

What some of us have done in the past is to create a userChrome.css file setting a top (and/or left) margin for that menu, which fixes the issue.

In the latest version(s?) of Firefox, this no longer works (but other userChrome.css rules I have set up continue to work), so I'm assuming that the ID of the context menus has been changed. What is the ID now?

Hi,

I got an issue that bookmarks are saved in the library, but this doesn't reflect on the Bookmark toolbar.

I have already removed the entire profile, did a reinstall .. nothing seems to reset it. When I perform a backup, the entries are also in the backup json.

I hope somebody can help, this started happening recently it seems.

Thanks in advance!
