Firefox already has <a href=\"https:\/\/support.mozilla.org\/en-US\/kb\/profiles-where-firefox-stores-user-data\">user profiles<\/a>, which allow you to hold units of settings and credentials separate. With some further effort, you may even launch a number of separate cases of Firefox with totally different profiles. Containers make related performance a lot simpler: every container has its personal set of saved credentials. So, as an example, a &#8220;residence&#8221; container may maintain a set of tabs logged into numerous websites along with your private accounts, whereas a &#8220;work&#8221; container may log into the identical websites along with your day-job credentials.<\/p>\n<p>There are additionally new options for customers on cellular.

It does make us surprise if MZLA is struggling to maintain up with Firefox&#8217;s month-to-month launch schedule, as it has been doing since <a href=\"https:\/\/www.theregister.com\/software\/2025\/04\/30\/thunderbird-joins-firefox-on-the-monthly-treadmill\/1246178\">Thunderbird 138 in April 2025<\/a>. Since Mozilla determined to speed up Firefox to\u00a0<a href=\"https:\/\/groups.google.com\/a\/mozilla.org\/g\/dev-platform\/c\/qlaQ1YSlOP8?pli=1\">fortnightly releases<\/a> from September, maybe MZLA ought to drop Thunderbird again all the way down to annual releases.<\/p>\n<p>Nonetheless, this ESR brings enhancements to folder dealing with, notifications, OpenPGP encryption, OAuth login, handle guide export, PDF dealing with, and rather more. There will not be any extra 32-bit Linux binaries \u2013 becoming a member of Firefox, which did that <a href=\"https:\/\/support.mozilla.org\/en-US\/kb\/firefox-has-ended-support-32-bit-linux\">in September after Firefox 144<\/a>. &#8220;Junk&#8221; mail is now referred to as &#8220;Spam,&#8221; and the devoted setup choice for the Russian <a href=\"https:\/\/en.wikipedia.org\/wiki\/Odnoklassniki\" target=\"_blank\" rel=\"nofollow\">Odnoklassniki<\/a> service has been dropped, with customers directed to configure it via XMPP as a substitute.<\/p>\n<p>Thunderbird provides so many alternative views that we have seen some consumer confusion about this, however they&#8217;re useful, and some of the non-default ones are improved on this launch. We typically use the &#8220;Unread Folders&#8221; view, and it is now higher at hiding folders with no unread messages. The opposite non-obvious view is &#8220;Unified Folders.&#8221; This categorizes and combines a number of inboxes into one tree: all of your inboxes, adopted by separate per-account bushes of all subfolders. It sounds complicated, however we discover it very useful. This view now permits you to color-code totally different accounts.<\/p>\n<p>A number of of Thunderbird&#8217;s new choices round account dealing with concern Thundermail accounts. These are a part of MZLA&#8217;s paid e mail service,\u00a0<a href=\"https:\/\/tb.pro\/en-US\/\">Thunderbird Pro<\/a>. This hasn&#8217;t been launched but, however the brand new account kind suggests it is getting shut. Probably the most seen indicators is within the Account Hub wizard for including messaging accounts: it now has a &#8220;Sign up with Thundermail&#8221; button on the high. <\/p>\n<p>This vulture is on the ready checklist, and we are going to report again after we get to the entrance of the road.\u00a0\u00ae<\/p>\n<\/div>\n<iframe data-lazy=\"true\" data-src=\"https:\/\/www.fiverr.com\/gig_widgets?id=U2FsdGVkX18x7XQvttUTrv1oEqmGNGTgvvCUiUoJ\/AP4z\/UyMz8lXGOLpu15jIMxBbTR0gmD5uBoFvhC4KWeALQRp3h\/X\/AwcVD0K8Wj9H\/ZzYKzcCNHosB9oS4SCJJFWiN85P9ICAc4OgCoE\/wHKIY7CDkf2\/DQ1vqGvk4smVe5cRDEmrLPCWi4FC8p40VUhSmWQ5udCm0zoJtorgWv3vbDQw0kKYkwn39ozAnQXDe+YvWMxkLFWA+O3TFwkJvdkIK+\/AUSnRssPKt5WHY0FhNOxnSPcLslEL4G4\/RfP95ve99U+kRnDy3X+KtzdQLY+u935ghON\/o3UE4IMv9oN6JX9RnxzL\/LRcOgnHigxStSGPKsZYtnz8RWNVT\/rOLAibqiWJadC5MYHRbekF3eg6FOGrQGkXYbsn0+a5aovnlLCbLwIqY9fcS17UX8J235iQ6cdmHNbrPeS84CMm34RA==&affiliate_id=1052423&strip_google_tagmanager=true\" loading=\"lazy\" data-with-title=\"true\" class=\"fiverr_nga_frame\" frameborder=\"0\" height=\"350\" width=\"100%\" referrerpolicy=\"no-referrer-when-downgrade\" data-mode=\"random_gigs\" onload=\" var frame = this; var script = document.createElement('script'); script.addEventListener('load', function() { window.FW_SDK.register(frame); }); script.setAttribute('src', 'https:\/\/www.fiverr.com\/gig_widgets\/sdk'); document.body.appendChild(script); \" ><\/iframe>\n<br \/><a href=\"https:\/\/www.theregister.com\/a\/5276390\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>SOFTWARE Mozilla partitions off your on-line identities as MZLA unleashes a bumper restore job Mozilla launched Firefox 153 on Tuesday, intently adopted by MZLA with&#8230;<\/p>\n","protected":false},"author":1,"featured_media":136366,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[],"class_list":["post-136365","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-tech-universe"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Firefox 153 contains itself while Thunderbird 153 fixes almost everything - mailinvest.blog<\/title>\n<meta name=\"description\" content=\"Technology is forever changing, and there are always new pieces of technology to replace obsolete ones.
