Manage Extension pages for each Add-On is informational only; does not allow me to disable extension etc. I haven't made any changes to extensions or customized Firefox in any way since the beginning of the year. Seems bizarre as seems to have happened rather suddenly.

Additional help suggestion offered by Firefox: * Shockwave Flash 32.0 r0 installed. No idea what to do about this; if it relates to Adobe Flash Player in Mac System Preferences, system plug-in is up-to-date.

Latest version of Firefox for Mac.

Thanks for any help.

Am running Firefox 68.0.1 (64-bit) on Win10. When visiting google pages, in both normal (logged-in) and incognito mode, firefox faults. When visiting google fonts page, the browser faults completely. When visiting google developer pages, firefox does not display selection and navigation icons (which are SVG objects). What setting in my firefox configuration may be causing these problems? The attached screen shots illustrate. Surprise: none of these conditions exist in Chrome. They also do not exist in MS Edge.

On a few websites, when asked to enter some information in a pop up window, after entering the information, the "submit" button at the bottom of the window does not work, and the pop up window won't close. Notably: paypal shipping and FedEx email tracking results. I have to use a different browser to make it work. Long time issue with firefox here; have tried refreshing, deleting cookies, cache, etc. Nothing helps

I'm using Firefox 68.0.1 on macOS Mojave 10.14.5. When I go full screen, the tabs and address bar remain at the top of the screen. I can't make them go away. I've tried:

- Installing plugins (I tried a couple) - Disabling Add-ons (Safe mode) - Resetting Firefox - Disabling hardware acceleration (and restart browser) - Using different techniques to go full screen (Cmd+Shift+F, Cmd+Ctrl+F, Zoom menu) - Scrolling or clicking in the canvas to ensure focus

No matter what, the tab bar and address bar remain on the screen (see attached screenshot). I've also attached my browser config (filtered on "full"). Is there any way to get a full-screen experience in Firefox?

importing my bookmarks i've done a mess.... a good ammount of them was duplicate or even more.

in a sense I've got the best redundancy in my bookmarks due to my attitude in importing edge to google, google to ie, edge to ie, and so on... but now, that i want to switch to only FF on all my devices, my list is super long, super redundant and super annoying (i've probably imported twice some of them).

due to differents time of usage not all my import are equally categorized in folder, cause in time they're changed a little, so that a classic deletion can't be the solution.

1 can i merge them to find duplicates to be deleted? that could help me in shrinking them before a good re-categorization.

2 if not.. how can a "magical merge button" be introduce to developers and community?

bye

For months, on my iMac desktop computer, Facebook does not work. It just spins and spins. So I have to have two browsers open and toggle between the two. Would prefer not to. This is not a problem on my Mac Book. There is also another website (Tempest - SayMedia) that also has not worked for just as long. I just noticed a Firefox update and got all excited, but NOPE, still not working. I use these both for work and I hope that someone can help me.

I know I can log into my Firefox account, because it allows me to update my profile (incl. changing password) and it has allowed me on to this support site. But I cannot find how to get it to allow me to use Firefox Send. I have been successful in getting into Firefox Send twice on different days in the past. Each time I persisted in logging in over and over again until (unpredictably) it took me to the screen for uploading files up to 2.5GB. I don't believe I do anything different when it lets me in - there are not that many different "Sign in" buttons or links to choose from. Firefox is my default browser. It says it is up to date. My Content Blocking policy is "Strict" but the little (i) at the top of the screen does not say it has detected blockable content. My cookies are deleted when I exit Firefox. SOMETHING NOT YET TRIED: I have just added https://send.firefox.com/ to the list of sites allowed cookies all the time. Will try exiting Firefox and log in again...

OK - enough space to comm.

I just built a Win 10 system (Pro x64) . In the process I built my standard batch file to backup my data files and Bookmarks to my removable HDD. I used the C:\Users\<your Windows login username>\AppData\Roaming\Mozilla\Firefox\Profiles\ path described in "Profiles - Where Firefox stores your bookmarks, passwords and other user data" article and found a series of files in a sub-folder identified as xbh4bkna.default-release\bookmarkbackups. So the associated line in the batch file reads "xcopy C:\Users\Oscar\AppData\Roaming\Mozilla\Firefox\Profiles\xbh4bk~1\bookma~1\*.* R:\BUs~1\Bookma~1\ /d /s". However, when I execute the batch file I get a "file not found" even through a directory search shows 6 daily files. Any suggestions on how to fix this? Thanks.

I tried to play videos on <ondemandkorea.com> on Firefox - I got their usual "AdBlock detected, buy our membership!" message. So I disabled my uBlock Origin - still the same message. I uninstalled the extension completely - STILL the same message!!! I tried the same webpage with Chrome - it runs, even with uBO installed, but with ads, even with uBO installed. The only thing I could think of that has any bearing on this phenomenon is that terrifying expose that was published a few weeks ago about how ad-friendly and overtly data-hungry Chrome has become in comparison to most other web browsers. I would be loathe to change how Firefox handles my private data, but I'd like to at least know HOW to get videos to play on <ondemandkorea.com> so I can have some options. Can anyone help please?

p.s. Googling uBO subreddit and forums and trying to make sense of their code with my limited knowledge was ineffective - in my experience, ondemandkorea devs update their code pretty frequently whenever someone publishes a workaround code for their aggressive adblock-blocking. And so I haven't really seen any recent updates that deals with <ondemandkorea.com>... at least none that I've found.

Since the Windows 10 1903 update which installed last week our three laptops have all developed a problem when trying to print selected webpages in Firefox. Selecting ALL in print range works OK. Selecting PAGES FROM 1 TO 3 (for example) results in the error. See attached photo. Pressing 3 may eventually get a 3 in the TO box. Often, any other number may appear or even a blank. I have followed the printer reset procedures in article http://mzl.la/1BAQqop and re-installed the printer too. Have run FF in safe mode. In all cases the problem persists.

Have tried Edge and IE both of which work OK and they have different looking print routines.

All three laptops have Roboform password manager extension installed. One laptop recently developed a problem when typeing the master password. Incorrect random charactors were being entered instead of the chosen keystroke. Verified by using a keystrike logger.

Any info and help would be gratefully received

I'm using Windows 7 and have recently encountered this problem (I say recently - last month to 6 wks). I can enter my login details, but when entering memorable data it's as if Firefox just freezes - the window looks like it's trying to move on, but never does. If I then try to access different sites, I end up with the same problem there too! I have to end the firefox process in order to use other sites again. Oddly enough, I don't have this problem on IE 11.

I keep multiple tabs open in multiple windows. Firefox v67 has done a good job saving/restoring all of them each time I launch the program. When the browser informed me of the v68 upgrade, I allowed it to install. At first launch after the upgrade, I was presented with a single fresh FF window with no history and no options to restore previously closed tabs/windows. I fiddled with it a bit... investigating options, closing/re-opening the browser, trying to see if there was anything to recover, including peeking into FF's disk storage, but to no avail. I began opening new windows/tabs to rebuild my normal setup. After a couple of days, from within a non-browser app I launched a URL (like pulling up online help). In response to that system request, a separate instance of FF launched and this instance restored all of my original pre-upgrade windows/tabs! And note these are separate instances (see attached photo of Process Explorer). So for example, I cannot drag a tab from a window in one instance and drop it onto a window in the other instance.

So now the big questions: What is the minimum amount of tab/window loss I can incur by shutting down each instance? In what order should I shut them down? When I re-launch after closing both instances, will FF only restore one set of windows/tabs? And will it be from the most-recently-closed instance?
