A while back, I had some very bad cataracts. In order to view text more easily, I somehow managed to change black text against a white background to white text against a black background in the pdf reader's settings. A side effect of this change was that color became grayscale. I would now like to return the settings to default. I've lost the article on how I made the changes. How can I get the pdf reader back to it's default settings?

I've tried uninstalling and reinstalling Firefox. The settings did not change.

Help!

Copying text with the latest version of Firefox 127.0.1 (64-bit) does not catch all lines of a page and its text the marking of these lines are ignored the same page text works if using Chrome

Those marked grey (in attached file) are the only that are captured as all the rests are left out even if they was intended to be marked .

Any help would be appreciated!!!

I found that my session activity on a secure (logged-in) website was being interfered with. I could not log-out of that website. After I closed Firefox, a notice appeared that an update was in progress. Why should a Firefox update interfere with an active session? Is this an updating issue that needs fixing?

For over a month now i have a problem with youtube. It loads videos very badly. I have good connection speed, but 0 network activity and 0 buffer health in Stats For Nerds on youtube and videos dont load. I can wait for 10-15 minutes (but sometimes they load almost instantly) before video load 40 sec buffer and after that buffer ends i can wait for another 10 minutes befor it load buffer again.

This problem persist only in my firefox on my computer. I tried deleting all the extensions, reinstalling firefox, "refresh firefox" future, changing useragent, reinstalling windows (it was the time anyways) but it doesnt solve the problem. I dont have this problem in other browsers (edge, librewolf, chrome) on my computer.

For the last several weeks (can't give an exact date, but it's been more than just a couple weeks, less than a couple months), both my husband and I have had issues loading videos in FF. We both have the latest version of FF. I went thru "Fix common audio and video issues" and did all those things, as well as trying to load the videos in troubleshooting mode. Nothing has helped (tho now that i cleared all the cache, i'm gonna have to log back into all those websites :( ). Nothing else is problematic. Our internet connection is fine. In fact, my husband has resorted to using MS browser to watch videos--they load fine in that browser. I have no other idea what to do. Searching your database for "youtube videos load slow" only resulted in a couple hits with no resolution. Hopefully this isn't the third. thanks

I think the v127.0.2 fix to the Youtube buffering issue also fixed the frames being navigated in the wrong order when using < and > to navigate frame by frame. For several months it would occasionally skip a frame with one tap of the button then show the frame it should've shown when you tapped it again.

I was sitting playing on the computer, I go to firefox browser and go to zelenka.guru, I look, and I'm not in an account on this site for some reason. I decided to go to another site, but there is the same problem, as I realized - for some reason I got out of all accounts on all sites.

My laptop uses Window 11. On the web Bet365, I view live streams video by Picture in Picture mode of Firefox (hotkey: Ctrl+Shift+]) and see that the quality of video is very bad. I tested with Chrome and didn't see this issue. Is there any way to improve video quality of Firefox Picture in Picture mode?

Thanks!

I just bought a new MacBook Air to replace a Windows 10 laptop which crashed about a week ago. I have my files backed up with Carbonite. I have found and downloaded a copy of my Firefox profile from Carbonite's website. I wanted to restore the profile to the new Mac computer. I have followed the instructions I found online to copy the specific files to the new profile. I finally got the bookmarks file to work, so my bookmarks are now transferred to the Mac. However, the passwords are still not showing up when I copy key4.db and logins.json to the new profile on the Mac. What can I do to get the passwords copied and restored to the Mac?

I do not know what version of Firefox I was running when the profile file was last backed up, but it was supposed to be running the current version when the laptop crashed last week. However, Carbonite shows the date of key4.db to be April of 2019 and the date of logins.json to be 10/8/2022. Should the files be newer? Would they be from an older version of Firefox that's not compatible with the current Mac version? I also just noticed that even though the bookmarks folder was dated 6/9/2024 in Carbonite, the restored bookmarks do not show some fairly recent bookmarks I added earlier this year. Is there any way to get my files back?

The Windows laptop that crashed is stuck in a loop and says it's trying to repair the hard drive. Is there a way to get it turned on but not booted up and connect it via a USB cable and transfer files to the Mac that way?

Thank you.

Hello all. Having updated Firefox a few days ago, we can no longer sign into Instagram. This happens only on Firefox, only since the last update, and Firefox is the same browser we have been using for years with Instagram. The problem is the cookie permission window for Instagram a) will not make a selection and b) will not disappear/close. We have attached a screenshot. There are no close tabs/buttons anywhere on this window, and we have looked the full length of the expanded window. As we have not changed any other setting, have not added any software, and this only happens on Firefox, we can only conclude that we have missed something which may have changed or been upgraded with your last update. This is quite urgent, as this is to manage the Instagram account of a wildlife conservation charity. So far we have tried reinstalling Firefox, clearing cookies, and deactivating/uninstalling all add-ons, however this has solved nothing. Could anyone suggest a solution please? Thank you for your time and assistance.

Hello! I have the latest version of the Mozilla browser installed. The entire interface is installed in Russian. Mozila has a service for automatically translating website content into other languages. Unfortunately, the set of languages ​​does not include Russian, so that I could automatically translate information from sites, for example in Spanish, into Russian and read such information. In the settings I found a function to switch the language translation, but unfortunately there is no Russian language again. Please tell me how can I set up such a translation? Or is there no such service at all for the Russian language?

Hi,

ist the famous and great Mozilla FireFox Developer team aware of the issue and is working on it?

I am happey to describe in more detail if required. thx

For the past couple of days when I watch videos on YouTube on my iMac it's VERY slow to start. Sometimes it takes minutes, at which point I have to refresh, and best case it takes about 1 minute to start.

I have cleared the startup cache, cleared cookies and restarted Firefox.

Also, YouTube works normally on both Safari and Chrome.

Not a super 'tech' guy so any basic steps I can take are appreciated.

Thank you!

I'm getting this error when trying to access Instagram posts on here in the past few days:

Something Went Wrong

It opens regularly in every other browser I have.

Dear Firefox Team,

It has occurred to my Firefox Browser of the latest version of 115 with some websites I have recently visited however which appear 8 grids of blank or white pages under "Recent Activity" as attached with the image for your technical troubleshooting suggestion.

Those 8 grids of Recent Activity in the older version of Firefox browsers used to have shown colorful graphics or images representative of the recent websites I visited in the recent past.

May I know what I am supposed to do to recover those graphics or images?

Kindly offer any suggestion or solution?

Thank you for your kind attention.

Best regards,

Mr. Topaz Chiu

Hi! I have more than one device for Audio connected to my laptop. Obviously the default device provide by laptop but also I have a Jabra Headset EVOLVE 20 SE MS and Jabra Speaker SPEAK 510 USB/ Bluetooth. Also my webcam Logitech C930e provide a microphone.

When I use Google Meet, in Chrome I can select on Meet Audio Device Select the different microphone or Speakers but in Firefox I can only select the Default System Speaker.

I would like to know how to change between my Audio Devices for the output or can switch between my different speakers.

I recently switched from windows to Linux, and was using it for 3 months now. It was due to window recall Feature. But still i was using chrome as default and daily browser. I wanted to explore firefox, its great actually, except 2 things which might need me to switch back to chrome or brave.

1. it don't have fu**king Profile switch, I mean i use 11 Profiles On Chrome, most people still use 2-4 profiles, how can we move to a browser that dont support profiles. I know we can add profiles by "about:Profiles" I tried it. It worked but guess what? To switch profile i have to manually go to that page to launch it. So much time consuming and frustrating. Why not simply add a btn on profile pic like chrome to switch profiles?

2. Add-ons is good thing, but there should be a way to install things from chrome web store, i not found any.

If firefox can fix these two things firefox can simply grow back to 30+ % market share, but if not people will just test l;like me and go.
