Diễn đàn hỗ trợ Firefox

Hello!

A little background info on what we're dealing with here. I work in a store and we own two workstations. Each workstation shares our two printers. One is a Star Receipt printer, the other is a Brother full size paper printer. Now Workstation2 is working without issue. We are able to print with the system specific default printer settings and nothing changes between printer. All good to go.

Now the issues stems from Workstation1. Our Star Receipt printer is set to print '77MMXRECEIPT', however when we select the Brother printer from the drop down menu then switch back to the Star Receipt the default paper size is forced to 'Letter' which causes the Receipt to print like a large sheet of paper which means we only get a portion of what we are printing.

This wouldn't normally be a problem, but due to some undefined steps(I'm not the only user and we don't always print from one website) the Brother printer is changed to default in Firefox which means that when we select the Receipt printer for printing, the default is again set to 'Letter' until we go to File>Print and set it to default again with '77MMXRECEIPT'.

Here's what I've done to test where the issue is this. I've changed and confirmed that when the Receipt printer is forced to 'Letter', the windows printer settings for both printers does stay on the default settings. I've also confirmed that the printer settings work on all browsers but Firefox and within Firefox I have gone into the .js settings file and deleted anything mentioned as 'print_' as well as going to Help>Troubleshoot>Refresh and completely setting all settings to default with nothing changing. I've also gone into About:config and tried resetting the default printer to no avail. The setting is always forcefully changed to 'Letter' when first switched to Brother printer and back to Star Receipt printer.

My take on it is there is some saved cache or settings file that has recorded and saved the Brother settings along with the Star Receipt settings and sets them both when switched to Brother. I've attempted to check both workstations and compare settings, everything appears the same. I have no idea where else to go on this as I don't know Firefox that intimately. Short of reinstalling Firefox I've done all I can think of.

My current version of Firefox is 66.0.3 (64-bit) labelled as Firefox Quantum.

Please let me know if there is anything you can think of! Thank you for your help.

When attempting to install any extension through Firefox addon's I receive a "Download failed. Please check your connection" message.

When attempting to install directly from an extensions website I receive a corrupt addon pop up box.

I've tried uninstalling my AV (Avast), changed the "xpinstall.signatures.required" from true to false.

Extensions install successfully on other browsers (Edge).

Firefox 66.0.3 64-bit Windows 10 Home Version 1809

Similar to the question here https://support.mozilla.org/en-US/questions/1239720 I'm finding that on a Mac I'm getting inconsistent results. If I hold CMD while clicking on a link in Gmail then I will be taken away from the tab I'm currently looking at and straight to the new tab.

If I'm on other web pages holding CMD and clicking on a link means that the new tab will open in the background and I will stay on the current tab. This is the expected behaviour and is consistent with Safari, Chrome, and other browsers.

How can I stop FF from taking me away from the tab I'm currently viewing?

Updates – Last updated 14:35 PST May 14, 2019. We expect this to be our final update.

• If you are running Firefox versions 47 – 56: install This Extension to resolve the expired security certificate issue and re-enable extensions and themes.

Updates – Last Updated: 17:04 EDT May 9, 2019

A less technical blog post about the outage is also available. If you enabled telemetry to get the initial fix, we’re deleting all data collected since May 4. (May 9, 17:04 EDT)

Mozilla CTO Eric Rescorla posted a blog on the technical details of what went wrong last weekend.

Updates – Last Updated: 19:28 EDT May 8 2019

We’ve released Firefox 66.0.5 for Desktop and Android, and Firefox ESR 60.6.3, which include the permanent fix for re-enabling add-ons that were disabled starting on May 3rd. The initial, temporary fix that was deployed May 4th through the Studies system is replaced by these updates, and we recommend updating as soon as possible. Users who enabled Studies to receive the temporary fix, and have updated to the permanent fix, can now disable Studies if they desire.

For users who cannot update to the latest version of Firefox or Firefox ESR, we plan to distribute an update that automatically applies the fix to versions 52 through 60. This fix will also be available as a user-installable extension. For anyone still experiencing issues in versions 61 through 65, we plan to distribute a fix through a user-installable extension. These extensions will not require users to enable Studies, and we’ll provide an update when they are available.

"Updates – Last Updated: 11:51 EDT May 8 2019 (From Mozilla Blog)

Firefox 66.0.5 has been released, and we recommend that people update to that version if they continue to experience problems with extensions being disabled. You’ll get an update notification within 24 hours, or you can initiate an update manually.
An update to ESR 60.6.3 is also available as of May 8th. We’re continuing to work on a fix for older versions of Firefox, and will update this post and on social media as we have more information."

A Firefox release has been pushed — version 66.0.4 on Desktop and Android, and version 60.6.2 for ESR. This release repairs the certificate chain to re-enable web extensions, themes, search engines, and language packs that had been disabled (Bug 1549061).

There are remaining issues that we are actively working to resolve, but we wanted to get this fix out before Monday to lessen the impact of disabled add-ons before the start of the week. More information about the remaining issues can be found by clicking on the links to the release notes above. (May 5, 16:25 EDT)

"Last Updated: 00:54 EDT May 5 2019

Updates:

Some users are reporting that they do not have the “hotfix-update-xpi-signing-intermediate-bug-1548973” study active in “about:studies”.

Rather than using work-arounds, which can lead to issues later on, we strongly recommend that you continue to wait. If it’s possible for you to receive the hotfix, you should get it by 6am EDT, 24 hours after it was first released.

For everyone else, we are working to ship a more permanent solution. (May 5, 00:54 EDT)

There are a number of work-arounds being discussed in the community. These are not recommended as they may conflict with fixes we are deploying. We’ll let you know when further updates are available that we recommend, and appreciate your patience. (May 4, 15:01 EDT)"

~Pj (Yeah! My Extensions Are Back!)

So today on my work computer ( i am still having issues with my personal computer(s) 10.6... ( see/read the previous ticket which is been closed not that it solved anything) because lastpass addon signature signing is not valid according to Firefox and nor can I download an older version that is compatible ). I went to do something on my work Firefox profile which I just recently created less than a week ago. I immediately noticed that tree style tabs was not open for some reason so I went to toggle it back on because sometimes it gets popped off, I couldn't find the icon so I went over to add-ons where I immediately notice that I had "no"? add-ons I'm sorry they're called extensions now in the new button that said unsupported. And guess what was in the unsupported category lastpass and tree style taps with a big message about not being verified and that I should click for more info which tells me to contact the developer and blah blah blahat signing is required in Firefox 57 and above.... and now all of a sudden Now I have a big yellow bar "one or more add-ons cannot be verifiedd and has been disabled". So I went back and looked at the version of last passed since I apparently have an outdated version!!! 4.27.2.10 last updated May 2nd 2019 okay so what's the next course of action? I can either remove the addon or find a replacement, find a replacement doesn't find lastpass. However a search does, and guess what version it is............ it is the same version! If it weren't for auto fill on IOS and android I would go back to a text document because this is getting ridiculous, because it is not on all of my devices and it spontaneously disappears.

I know this is a Firefox problem but this will require going to Mozilla to get this thing fixed.

That's all I can think of for now other than frustration frustration frustration frustration frustration and I probably need to reopen my old ticket, which said wait for an update that we'll never come because the addon system changed.

So I just went to my personal profile, same issue. Both profiles have been open ) simultaneously with no issues( since yesterday with the only thing changing that the computer has been put to sleep and woken back up. Here's a screen shot of all my add-ons on there..... Oddly enough the only thing that survived is "multi pass" which I haven't gotten around to touching yet.

So I just closed out of everything, unchecked reopen windows on login, did a full restart. And my work Firefox profile has my 2 extensions back but my personal profile does not. And Firefox things "these extensions do not meet current standards so they have been deactivated". My work computer is brand-new and I received it in October .... so? My personal Firefox profile was created in October or November 2018, and work profiles was created within the last two weeks (i moved from Safari too many tabs and i needed side tabs...). All should have current add-ons using "current standards" but Firefox doesn't think so?

I know this is a Firefox problem but this will require going to Mozilla to get this thing fixed, so well unlikely I will be CCing to firefox/Mozilla.

This is a hard one to provide steps for reproduction. The next time it happens I will take a screenshot.

The issue is as follows:

I'm on a 64 bit Ubuntu 18.04.2 LTS machine, with Firefox 66.0.3 installed. Every now and then (roughly once every 1 or 2 hours) I will do something in the browser, whether that be open a new tab, press play on a YouTube window or something else, the window will turn invisible. The frame of the window with the name of the tab up the top is still there, and I can drag it around no problem, but the actual content of the window is not there, I can see straight through it. At this point I've sort of ruled out it being an OS related issue, as Firefox is the only program on my system that seems to have this issue.

Any help would be much appreciated.

anything which streams content wont work on my firefox, it either needs an update to the browser or a plug in but i have installed the nessecary plugins and add ons and updates and yet it still won't work

Sometimes with nothing that predicts , Firefoz start eating all resources of my computer , and I can't work anymore until a cold shutdown , what it annoy me , is the Firefox can try allocate 0,4 Tera bytes of memory when my computer just have 4 GB bytes .

ulimit -Sv 10000000 [1] seems that limit Firefox to ought all memory , but can't Firefox be more intelligent ?

More info local news tend to have lots of ads I use ABP (ad block plus) but sometimes they have so many scripts that seems they enter in loop, but Firefox should limit the consume of the resources . Another info this is not nothing I see this problem for at least 4 years , I expect that Firefox Quantum solve the problem, now that I use 66.0.3 without any legacy plugin this still happens or it is worst .

It disabled my ad blocker and my Kaspersky Protection add-ons yesterday. Running latest version of Firefox and have verified that the hotfix is active as shown on the support page but still getting the exact same error when I try to add any add-ons. "Download failed, please check your connection."

There is a persistent device control box after I close the tab that uses it and I must restart FF for it to go away. It follows me to all virtual desktops and is really annoying and distracting.

I am on Arch Linux i3 window manager and using FF 66.0.3 64-bit

Add-ons such as AdBlock Plus have suddenly been disabled with no way to re-enable them. I have tried re-installing firefox. Now my add-ons are gone and when I try to install them from firefox's own website, it tells me "Download failed. Please check your connection." My connection is clearly fine since I'm able to be on this page. What is going on?

Firefox 66.0.3 is constantly crashing on Windows 10 64bit. It doesn't matter if I am actively doing something or if it is idle. The frustrating part is there is nothing in about:crashes to indicate why this is happening. I've tried reinstalling, refreshing, etc. to no avail. Any assistance will be greatly appreciated!

Suddenly most of my addons have been disabled because "they can't be verified" or some BS.

Who in his right mind thought this was a good idea?!

DO NOT make such decisions for your users. Trust can only be achieved if you DON'T enforce it.

HOW TO ENABLE MY ADDONS?

Following page pops up every time I try to download. It has never happened before. Is this a virus?

For the extension to execute external commands (start the external download manager for instance and send links to it) one extra step is required. Please download, unzip and install this minimal native client to allow the extension to communicate with the external side.

   Click here to download the ZIP package for your operating system or click here to browse all available download options.
   Extract the downloaded package into a local directory
   Now double-click the install.bat file

I have Windows 7 64 bit and was using Internet Explorer 11 for years, but have now downloaded and installed Firefox version 66.0.3 (64bit). After searching the community I have set up my home pages etc. I also have Norton Security installed and when I did a search using google, Norton did not rate the search engine results. I have checked the extensions and Norton Safe Web is listed and enabled,(it says disable or delete by the side of it). I have searched help and the community but cannot find a answer to my problem. I would be extremely grateful for any help. Thanking you in advance.

When I enter any about: item ff takes over 2 minutes to load & comes up with an error message "Can't connect to 192.168.1.200". Now that's an old local server which is no longer in use, and obviously the IP is still somewhere in the settings so ff is looking for it. I've checked every item under about:about but can't find the IP, where could (should) I look. Thanx

Gab.ai is displaying a blank page in Firefox but works fine in Chrome. Is anyone else having this problem? Has Firefox started censoring websites?
