Hey there, awesomes! I'd like to change my Firefox pdf viewer's background color (both sides of the pdf) to dark, currently it shows light gray (see `background_bg.png`). And here is effect I want it to look like (see screenshot from Chrome `wished_bg.png`). Thanks in advance (:

PS: I don't want to change my theme to dark. It seems I have to change my css, but I dunno which & how.

When trying to install addons from Firefox addons management menu (tab 'about:addons'), they not downloads. and Firefox says 'addon can not be loaded because connection problem'.

When trying open 'https://addons.mozilla.org/ru/firefox/' have 'PR_CONNECT_RESET_ERROR'.

I am thinking the reason of this errors is blocking requests to 'addons.mozilla.org' by my internet provider (Beeline Kazakhstan). Because when I trying to connet to 'addons.mozilla.org' using VPN or proxy I have no problems described above.

I have no idea why this internet provider or goverment needs to block host 'addons.mozilla.org' (they love to block various website just fo fun). May you help me bypass this problem? May be you know the way how to install VPN addon offline for Mozilla Firefox whithout acces to addons webpage.

Sorry for my English and thank you for reading (:

I have recently changed from using Microsoft Online to GMail service (not by choice). I now have a problem in that I cannot send emails from TB because TB still wants to sign in to the Microsoft SMTP server, not the GMail SMTP server. I have tried various strategies, including delete / recreate account, but TB insists that I need to log in to the MS server. So atm I am receiving / viewing emails in TB (because I prefer TB), but sending / replying via GMail. Please help.

OS = openSUSE Leap 15.2 TB = 78.6.0

Hi, (This appears to be a long-term problem, spanning several versions of Thunderbird.)

My webmail sent folder contains emails I've sent from my phone (various apps, incl Bluemail), however, NONE of the emails I've sent from Thunderbird on my laptop are stored in my webmail account.

My provider is Westnet (Australian) and they are investigating, but I'm keen to see if any other TB users have resolved a similar problem, and if so, how? Thanks, G.

I can't find any results about this, so not sure if it's a stupid idea. It does seem quite reasonable to me, though.

Does anyone know if it is possible to disable an inbox? (NOT delete)

Or has anyone come up with a reliable way of not displaying a specific inbox, but still having the account details saved? i.e. Disabled or hidden until I specifically click on it and list the e-mails.

I think it would be cool to have something like a hybrid unified/account view, so I can select which inboxes I want to unify or group into a 'view'?

I use unified inboxes, but I have a couple of accounts I don't need daily access to, but I still want to keep the account details stored so I can check on them if I need to.

(Also, is it worth asking Mozilla for a feature or is it just pointless?)

Anyone else think this would be of benefit to them?

Hi!

How can I fix Thunderbird?

Within seconds of launch, it crashes.

I am running Windows 7 Pro (64).

This problem began during the second week of November, 2020.

Because of the instantaneous crashes, I don't know how to tell you what version of Thunderbird I am using.

I have been using Thunderbird for more than ten years. I suspect that some of my profile folders are large.

I am attaching a screen shot of 'Crash Reports'.

I appreciate your help, and look forward to hearing from you.

Hello As others have said recently, Firefox has become unusually greedy in RAM!

I love Firefox and it's been my favorite browser for years and years. But there it became unmanageable for me!

I'm absolutely not going to spend money to add more RAM to my PC tower, which is only three years old, and otherwise performs perfectly well for my use with all my other apps. There is 8 GB of RAM in my PC, a fast model of RAM, very fast, and expensive. You have to stop, guys, and face the truth! There is a real problem and there is no point in denying it, and saying that it takes more than 8 GB on a PC at the end of 2020.

The CONCRETE result is that we are all going to change the browser we use, it's super sad, and it is happening NOW. I don't want to change, but I have no choice. It's kind of heartbreaking for me, believe me.

Installation of Thunderbird 78.6.1 disabled Lightning Calendar connection with Google. Provider for google Calendar is operational, No Lightning updates are compatible with this version (I understand Lightning might be included in the Tb download (?), but the only solution was to reinstall Thunderbird 78.6.0 and then all was well again. Help Please. Or is this subject for a bug report?

Attached is a sample of how web pages display. These can either initially display this way or, as in this example, the page opened correctly, I stepped away for a few minutes and when I viewed the page again it looked like the example. I can have a page open and it is displaying correctly, then open a new tab and go to a different site and the text will look like the example.

I have cleared the cache, dumped all the cookies. Restarting the browser (I do this many times a day) will fix the current page but eventually another page will display like this.

I running version 84.0.2 64bit on a Mac Pro Mojave. I don't have this problem with other browsers like Chrome or Safari. I never see it on my Windows 10 system.

Firefox displays pdf files very nicely, but how do I save the file to my download folder?

FF help says this is done by “clicking the download link” but I cant find any download links anywhere in the FF GUI, when the pdf is displayed.

I'm sure its there somewhere, but I just cant find it..

Help appreciated,

Cheers, Lars Bo

Hi, I have a weird issue if I scroll with my mouse down a webpage I'll get these jagged horizontal lines in the middle of the screen but go away when I stop. Also, when I watch a video where a lot of moving is happening like if it's a hockey game the middle of the screen just that jagged line across in just the middle. What causes this and how do I get rid of it I don't notice on Internet Explorer browser and I've tried disabling hardware and stuff but doesn't work.

I select the setting:

"ask to save logins and passwords for websites" so that I can also select 

"Autofill logins and passwords". This works for a session of Firefox, but when I close it and start a new one, it does not retain the selection. Is there another setting somewhere that is undoing it?

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "we need to restart to finish updating" <- this last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.

I have been using Firefox for many years now and it uses Google, but for the past week or so when I have typed in my search it automatically switches it to BING search. I have checked all my settings and programs but BING is not listed, so why the automatic change over, and how can I fix the problem?

Hi, as a user of Firefox from day1 I have hit my first problem so not bad going. Right, I have a win10 desktop(DT1) and 2 laptops (LP1 AND LP2). All win10 fully patched up &Firefox 84.02. This morning I noticed my network share from LP1 to DT1 wasnt working and found LP1 powered down. Powered it up & it looked to be completing a patch (KB4598242) so let it finish successfully and logged in. It wouldnt take the 2 master pw prompts although definitely typing them correctly. Poked around the forum that talks of key4.db, key3.db and logins.json. Only had key4db but had a loginsbackup.json. deleted logins.jason and renamed loginsbackup. reloaded. Same, so am stuck. Did notice as LP1 loaded after powering on that a Firefox update occurred. Could one have messed the other? Anyway these things seldom happen on their own so what went on yesterday. On LP2 I noticed that on each reboot I got 2 identical FFox windows. I tried refresh, uninstalling ffox & mainteneance service, same. So I searched for the word firefox and deleted everything I could find and reinstalled FFox. Same, so switched off & gave up. Perhaps I have sync between my devices, not sure. However I have never at any stage changed my master passwords which is the same on all 3 pc's. Any ideas? Shame to lose over 120 passwords if I have to somehow start over again by uninstalling FFox and reinstalling..that'll take ages. And of course the password prompt is coming up all the time whilst typing this. Help please

I have a problem with the firefox browser on my phone (Oneplus 7T). When I download a file, and then want to open it, the message "Could not open file" is displayed on my screen. For example, I tried to download word documents and pdf files, and it wasn't possible to open any of these two types.

I already activated the external download manager but it didn't change anything. I put firefox as my default browser but nothing changed.

I really want to switch from chrome to firefox but this problem is the main reason I don't...

Anyone can help :) ?

I am using the latest version of Thunderbird [= 78.3.1]. On the internet there are lots of ways suggested to turn off line wrapping, but none of the suggestions work for the latest version of Thunderbird. How does one turn off line wrapping?
