I recently copied my Old Firefox profile to another folder and refreshed my Firefox Dev Edition browser. After refreshing, I copied all of the content of my old Firefox profile to the new default profile and then started the browser. Upon starting it, the browser was working with all of my previous add-ons. But whenever I close the browser and open it again, the icons of the add-ons at the overflow menu are not showing though there is space for the add-ons. Whenever I click at the add-ons, the error that 'Access to file was denied' - `The file at moz-extension://b408b31d-945f-43cb-881e-b1f4071942b6/index.html is not readable` shows up. I tried it with creating other profile folders and then copying my old profile data but it still always happens.

Any help?

Does Find toolbar (Ctrl+F) have option 'Highlight All':'on' by default, so all occurrences are highlighted with pink background?

I write test case for Mozilla, and this question is critical for test.

When I go to a page with Vimeo content on it, the video displays as a blank spot on the page and will not play. How do I get this to display and play correctly in the Firefox nightly browser for Android?

Hi,

Straightforward issue I just noticed.

For some reason I cannot delete some of my bookmarks. Whenever through bookmark icon/manager. With right click context menu delete, delete keyboard button, or "bookmark remove" from shortcut.. etc.

It just doesn't function. I can move those "frozen" bookmarks around in folders and such, but I simply cannot delete them.

Suddenly Firefox hangs when navigated to next tab.

Also happens when Alt + tab to Firefox from other window.

Text is not typing in URL(address) bar of currently opened tab

Creating new tab button summons tabs, can drag tabs, but can't switch to any except one on which Firefox hanged.

Screenshot explains a little bit more.

I have Firefoxes with alomst identical default profile, lets say they are two Firefoxes on different machines. Perhaps their profile is a bit different, but mostly default settings

When I change preferences like on screen in one browser I don't see shield near url in address bar, but in another browser with THIS preferences I do see shield with both two checkboxes on or off. (Checkboxes for "Trackers" and "Cookies")

Which behavior is "default" or "normal" or "correct" for current Firefox version?

default checkbox's values were changing in different releases

Hello,

Both Firefox dev and standard are having a problem where if i leave my browser open for some time the CPU usage goes up and it will use all 32GB of my memory until it crashes my PC, this is a content thing.

I have tried clean uninstalling both and it has fixed nothing it has gotten so bad that i need to restart firefox every 30 minutes or so I might need to swap over to an other browser at this point.

thanks for any help i can get,

Thunderbird 60.7.1.

When using Thunderbird’s search field, the autocomplete offers me some email addresses that are not in the address book, nor in any emails. How to get rid of them?

I've followed all instructions, exported my Edge bookmarks, but I just don't have any access to them from Firefox. I'll have to uninstall and continue with Edge until this feature is made available.

I have multiple add-ons. I am using their functionality but I would like to hide them so it only shows 2 of them, without losing the effect of the others. How do I do that?

Just installed the most recent FF update and in the extension screen I now see some orange and purple emojis and the end of the different adds ons. What do they mean? See attached screen shot. Thanks

Guys after latest update I can't change fully my user interface language. I changed language setting to English everywhere, and part of it is still in Estonian ( I live in Estonia, that's why for some reason mozila gave me headache and changed user interface to estonian).

Check screenshot, English is set as main language and menu is still in estonian. I even reinstalled ENGLISH version of firefox, but it didn't help me, still estonian menus. Spend 2 hours trying to solve this issue. Sry for crying, but so often after updates things like this happen.

Please help me change language to English :)

P.S. I can't delete my profile in firefox, and completelly reinstall it, cos I need my setting.

Thanks in advance and have a nice day!

Everything worked fine since the last update,since then I changed all I could find related to language in about:config and also modified the options,even removed my language and changed it to english.What is the problem?

As of update to v68 I get errors like these: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at file:///D:/website/fonts/fontawesome-webfont.woff?v=4.2.0. (Reason: CORS request not http).

What the heck is this? Why did silly mozila messed up the development of local files? How can I bypass that WITHOUT ALTERING my code? It broke fontawesome functionality! Very stupid!
