Recently, unable to Open Microsoft Outlook email using Firefox 100.0.1 (updated June 10th, 2022). Able to open in Safari. Prior to this incident no problem with opening Outlook.

I've not been able to restore previous session of tabs and windows even though the box is checked in settings to restore prevous sessions. I've also tried all the troube shooting things. I really need this to work. I've been using firefox for many years. Please help me.

Despite clearing my cookies and cache, going through every step on [this web page|https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems#w_check-browser-internals], and trying multiple different Netflix profiles, I cannot seem to get Netflix to load any content on Firefox. This problem seems to have cropped up over the last few days; I last used Netflix on June 11th and had no problems, but tried last night and again this morning to watch anything only to find that it would invariably show me a red loading wheel before presenting me with error code F7111-1105 after several minutes. This seems to be an issue with Firefox on my PC, as I have tried using the Netflix mobile app and (reluctantly) installing Chrome on my PC to test things out -- both had no problems -- yet I'm stumped! Again, I have gone through every option presented by the troubleshooting page; I have refreshed and reinstalled Firefox, made a new Firefox profile and tried it out with no extensions, scanned my PC thoroughly (with no issues presented), and nothing seems to budge.

Firefox used to show our browsing history from years ago. Tonight we tried to access our history and all of a sudden it goes no further back than this month. How did this happen, and how can we get the older history back?

We have been researching this for several hours tonight and have already tried many of the suggestions such as viewing the places.sqlite file--which we did, but which also only showed history going to the beginning of June--trying to view the index.dat file--which came up empty using the index.dat analyzer reader--and trying to read a JSON file that is called "session store backups."

OS Windows 10

We know our way around a computer, more or less, but are not programmers or coders.

Autofill for payment and address information has stopped working. The option to choose one will come up, but when you click it, nothing fills in. Password autofill has been working, though.

Currently the fonts at the top of the page (tab headers, address bar, search bar, booksmarks) are all set to a larger font. I don't know how they got changed but they are too big now. If I try change font size and style in settings nothing happens. It is not how it looked on first install and using another browser has font sizes of a more practical size. I have tried uninstalling/reinstalling Firebox and also doing a refresh and it doesn't change anything.

Its almost like a bug that has made Firefox set these fonts larger than they should and not able to modifying them again.

I cannot for the life of me work out how to fix this and its very off putting to the point, short of a full OS reinstall I'll have to start using another browser.

Same issue as [this poster] . I've seen no correlation between pixelsPerPx and cursor size, but have noticed this behavior doesn't occur in Manjaro's version of FireFox, so I started asking myself, Self, "what might the differences be here?" Answer I got back: they (Ubuntu 22.04) have bowed to the god of SNAPpiness, and Manjaro still hasn't (gets updates from Mozilla rather than the snap store).

Am I on to something here? What else could be the difference between the two flavors of Linux? Any help would be greatly appreciated, my tired eyes have forced me to change default browser to Chrome or Edge, both of which don't seem to respect my privacy like Firefox. Interesting to note that Thunderbird doesn't have the "flea-size cursor" and it also is not using snap for updates.

My windows 10 pc is set to dark mode, my win 11 pc is set to dark mode, my firefox theme on both pc's is set to dark mode, my phone is on light mode. On my windows firefox which is updated on both devices the top bar will stay dark in dark mode (default firefox theme) but after certain pages it resets itself to light, is this because of my phone being on light mode and themes are syncing over? its extremley annoying and after using the debug: page to try and force darkmode i had to reset firefox due to debug causing issues, now im using an untouched firefox version and it keeps changing from dark mode to light mode!

The LastPass add-on has somewhat spontaneously stopped auto-filling passwords even though I have that option enabled. I assume this is a Firefox issue because my vault is there just fine and recognizes the website and passwords (just won't autofill). Has anyone else run into this issue? How did you resolve it?

Is there a way to autofill for most sites but not autofill for certain sites while still saving passwords through firefox for those sites. I like to store my bank information on firefox behind an master password but it automatically autofills with out asking for the master password. Can I limit the sites that autofill passwords or require the master password in order to autofill? Any suggestions?

Sometimes, if the computer is offline and Firefox is open, when the computer goes back online Firefox can't connect to any website, with the page "Hmm. We’re having trouble finding that site.". The only fix is to close Firefox and open it again. Going offline doesn't always do this, and while I'm not sure of what exactly causes this to happen, a way to easily reproduce it is:

• Turn off the Wi-Fi;
• Reboot the computer;
• Open Firefox;
• Turn on the Wi-Fi;

After the computer is connected, refreshing the page sends you to "Hmm. We’re having trouble finding that site.". You have to restart Firefox.

A way that doesn't 100% reproduce it, but works enough times, is to reboot the computer without turning off the Wi-Fi, and open Firefox as soon as possible (before the computer manages to connect to the router, which is the part that isn't always consistent). Rarely, it happens after suspending the computer, or after a disconnection due to an unstable connection. I can reproduce it in Firefox's safe mode. I have a hunch that maybe this is related to networking drivers.

I'm using a Lenovo IdeaPad 5 14ARE05 (Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)), Linux NixOS 22.11 (I don't know about Windows).

Ask me for any log you might need.

This is kinda a duplicate of https://support.mozilla.org/en-US/questions/1078253, except that their solution does nothing to me.

Hi All

I manage my cookies manually as I keep many tabs open permanently. Having to constantly log back in to those accounts would be onerous if cookies were deleted on close of browser. Managing this via manually adding the website exceptions function is also a drag.

Would it be possible to have a 'keep cookie list' that are saved when the browser is closed?

Cheers M

When I right click on an image in Firefox, and choose the "Copy Image" option, it never works. In fact, it hasn't worked in years for me, and that's on numerous PCs, with Windows 7 and Windows 10. I'm doing this so I can paste images into Photoshop. It looks like, instead of copying the image itself, it's just copying the image file, but this means I can't paste it into Photoshop.
