Firefox Support Forum

Hello. Forgive my broken English. for some time now I have not been able to print web pages from Firefox (on IE it works with the same pages). I followed all the instructions given here https://support.mozilla.org/fr/kb/corriger-problemes-impression-firefox but without success. Always the same message that says "an unknown error occurred during printing". I have completely reinstalled Firefox, but it's the same. Can you help me ? Thank you

I have Windows 7 and Firefox browser 79.0 (64bit).

I followed all troubleshooting steps: Firefox was "refreshed"; theme is default; all extensions were removed; hardware acceleration disabled.

Now, if I restart Firefox in Safe mode - the problem disappears. When I start it normally, the problem persists.

Can anyone help to troubleshoot this?

Thanks.

Hello experts, I have a problem: I had a session window open with 116 tabs open and I cannot re-open them after restert of FireFox. I use the newest Firefox version 79.0 (64-Bit) on Windows 7 Pro SP1 and the extension "Tab Session Manager" I closed FireFay and as usual, after I restartef it, I waited for the opening of the series of my previous opened tabs. FireFax opened 117 tbs but did not fill in the URLs. They were all opened as new tabs. So I tried to open FireFox with deactivated add-ons. There it was possible to restore all the tabs. After that I closed FireFox again and opened it the usual way. It opened 116 tabs but they were all empty. I used the Add-on manager to shut down my extensions leaving only the tab session manager, AdblockPlus, NoScript. After restarting te tabs were empty again. In the list of the tab session manager I could find the sessions with 116 empty tabs (see ErrorTabSessionManager0.gif) but also the last session with the original tabs. See image ErrorTabSessionManager1.gif. I could even save this list from TabSessionManager. I updated PabSessionmanager to the newest version but that did not help. How can I get FireFox to load these previous tabs again, some of them are very important for me ? thanks for any help Jochen

After a reboot of windows 7 some of my PC looked different then after a system restore everything looked fine except Firefox was back to its default. Tried swapping back to a previous saved profile, also blank. Started trying to restore my settings off a synced profile on an unaffected computer BUT noticed in the general settings of the options folder at the very top it says 'Your Browser is being Managed by your organization' underlined as a link' witch leads to http://www.null.com/ (Calacom.com) I have been hacked & Hijacked HelpI want to manage my whole browser again

For about the last 5 hours, when I download Firefox, nothing syncs after I log in -- no add-ons, no bookmarks, no history. I've seen no mention of this on the support page.

I first noticed this about 3 pm Sunday, EDT.

Is no one else experiencing this?

I have a serious "complaint" that Firefox 79 (32-bit) under Windows 7 Pro SP1 plus fixes does a very poor job of limiting its proportion of memory usage, or running cleanup automatically as per the about:memory "Minimize memory usage" button's action. Can some optimisation be done to alleviate this, say every 15mins perform this function automatically?

Workarounds: 1) Log off/Sign out of tab and close it. Open new tab and reload bookmarked URL. Move tab to former position, as necessary. 2) Close and re-open Firefox entirely.

Whenever I go to save a web page, I would say 95% of the time, when I look in the download history, it says failed. If you double-click on the failed page, then it downloads. The thing I discovered is that when I go to my downloads folder on my hard drive, the pages actually do save most of the time, even though the download history says failed. What is troubling is that when I double-click on the "failed" page in the download history, it will show the page being downloaded. But when I click on the saved page in my downloads folder, then the saved web page does not look at all like the original page. Instead it looks more like a text file with some photos on the page. The page looks disorganized. If I click to save the web page again, and let it say failed in the download history (I don't double-click on the page in the download history) then the page opens normally from my downloads folder. The thing that bothers me the most is that some pages that say failed actually failed. This creates uncertainty as to whether I can trust Firefox to actually download a page without me always going to my downloads folder to check to see if the saved page is actually there. Earlier versions of Firefox did not have this issue. I like being able to open a saved page from the download history, but that cannot be done if the download history says failed. I believe this is a glitch in Firefox.

hello, i started using mozilla again after years of not using it. the past few weeks have been good but i ran into an issue with a website i typically visit.

this web page http://davoonline.com/phpBB3/viewforum.php?f=3 http://davoonline.com/phpBB3/viewforum.php?f=3

when i click, i get a blank page with this text: Strict Standards: Declaration of phpbb\template\twig\loader::findTemplate() should be compatible with Twig\Loader\FilesystemLoader::findTemplate($name, $throw = true) in /home/content/43/5415943/html/phpBB3/phpbb/template/twig/loader.php on line 20

Parse error: syntax error, unexpected ':', expecting ';' or '{' in /home/content/43/5415943/html/phpBB3/vendor/twig/twig/src/ExtensionSet.php on line 70

the only solution i tried was turning off an my extensions and the one found here

Firefox 78.1 ESR W7

Is there any way to get the menu bar to have a unified appearance? Solid background mixed with a transparent one is not very nice looking. It would look much better if the solid background were also transparent. Anyone have a .css or other solution?

After update to 79.0 version, (on Win 7), the cursor totally disappear, an so it's really unconfotable to identify what I'm doing... Now it's possible to identify the cursor position only selecting some caracter, using mouse or case key + arrow. I tried to find some question on the web, and founded to set something in the "about:config" system, but in my list, for example, don't appear the "ui.caretWidth" row. I saw this problem appeared in 2017 too. (It appear NOW, for me...) I don't think to be the last person to use win 7... Can someone helps me?

I have a whole slew of tabs I use daily and Firefox is set to reload them whenever I restart Firefox. Now with version 78 it tells me it has to reinstall and won't keep my tabs, in other words I have to waste time setting all 200 of them up again. Several times a day it nags me to update and there is no option to tell it to Shut Up. If Firefox can't be bothered to provide smoother upgrades, I can't be bothered to upgrade.

Firefox v69.0 Whenever I click on one of the matches returned from a search, or click on an embedded link, Firefox forever highlights that selection even though I don't want to be reminded months later that I had looked at that site. This is irksome because I can't ever get a clean slate for doing searches. Every similar search will yield a page full of highlighted links I may have used in the past on a topic that is only tangentially related. Also, since this highlighting persists independently of clearing history it entails a severe privacy leak. If anybody who is authorized to use my machine suspects that I may have an interest in, say, pizza dough, they need only do a search for pizza dough on my machine and any link I had ever selected in the past is highlighted, from which links it can be easily determined that I have both an interest in the topic at large and what aspect of the topic in particular appeals to me.

How do I disable this "feature", please?

Hi. I'm a user of OpenVPN which uses TAP (a virtual network adapter) to establish VPN connections. Sometimes I need to switch VPN on/off when browsing websites, but I didn't find options like "select a network adapter to use" within Firefox. Currently the only solution is to connect/disconnect OpenVPN to switch VPN on/off, but it's quite inconvenient for me.

I've tried searching for add-ons about this, but a possible one named "FoxyProxy" has dropped this feature recently because of the changes about Firefox API, so I think my problem can be no longer solved by add-ons.

Any solutions to this? Can I have this feature provided by Firefox with updates if there isn't any workaround for now?

Using Firefox 79.0 | Add on NIMBUS | When I shutdown add-on Nimbus, it stops opening up a new focused Tab. However When I activate the add-on, it opens a new focused tab each time I open a new firefox session. It opens a focused tab pointing to: https://nimbusweb.me/capture-install/install.php I have tried several suggestions and it did not work. I've contacted Nimbus several times, however I did not receive a response. Thank you!

I have had Firefox set to delete cookies upon closure for several years now. I recently noticed that some cookies were present as soon as the browser was opened, which should not be happening.

This set of cookies reappears every time I open Firefox, even if I manually delete all the cookies, and even if I delete the cookies.sqlite file in between closing Firefox and reopening it.

This problem occurs on two machines with Firefox. One with Windows 7 and one with Windows 10. I have Sync configured to keep bookmarks the same on both machines. I was wondering if this may have something to do with it, as the same set of 'zombie cookies' keeps reappearing on both machines?

Hi, My Firefox and Thundebird internet download / upload speed is slow. I I try with Chrome download speed, it is 7-10Mb up and down. If do same with Firefox, then it is different. Many times it is 0,2Mb, but some time also 5-6Mb Usually upload are faster and it is 5Mb. (Use Chrome, then always faster) It seems to me as random, because many times speed OK and many times not OK. If compare test result with Chrome, then always slow.

I use ESET virus control and try to test it without virus control, but same result.

Also in Thundebird HTML load are slow. Small picture in e-mail can reach 30 sec.

I try to change different things in options, but no result.

Can anyone help me with this?
