Security update for MozillaFirefox, MozillaFirefox-branding-SLE
This update for MozillaFirefox, MozillaFirefox-branding-SLE fixes the following issues:
This is the Firefox Extended Support Release 140.0esr ESR
Major changes:
General:
- Reader View now has an enhanced Text and Layout menu with
new options for character spacing, word spacing, and text
alignment. These changes offer a more accessible reading
experience.
- Reader View now has a Theme menu with additional Contrast
and Gray options. You can also select custom colors for text,
background, and links from the Custom tab.
- Firefox will now offer to temporarily remember when users
grant permissions to sites (e.g. geolocation). Temporary
permissions will be removed either after one hour or when the
tab is closed.
- Firefox now includes safeguards to prevent sites from
abusing the history API by generating excessive history
entries, which can make navigating with the back and forward
buttons difficult by cluttering the history. This
intervention ensures that such entries, unless interacted
with by the user, are skipped when using the back and forward
buttons.
- Firefox now identifies all links in PDFs and turns them
into hyperlinks.
- You can now copy links from background tabs using the
tabstrip context menu on macOS and Linux.
- Users on macOS and Linux are now given the option to close
only the current tab if the Quit keyboard shortcut is used
while multiple tabs are open in the window. (bmo#None)
Sidebar and Tabs:
- You can now enable the updated Firefox sidebar in Settings
> General > Browser Layout to quickly access multiple tools
in one click, without leaving your main view. Sidebar tools
include an AI chatbot of your choice, bookmarks, history, and
tabs from devices you sync with your Mozilla account.
- Keep a lot of tabs open? Try our new vertical tabs layout
to quickly scan your list of tabs. With vertical tabs, your
open and pinned tabs appear in the sidebar instead of along
the top of the browser. To turn on vertical tabs, right-click
on the toolbar near the top of the browser and select Turn on
Vertical Tabs. If you’ve enabled the updated sidebar, you can
also go to Customize sidebar and check Vertical tabs. Early
testers report feeling more organized after using vertical
tabs for a few days.
- Stay productive and organized with less effort by grouping
related tabs together. One simple way to create a group is to
drag a tab onto another, pause until you see a highlight,
then drop to create the group. Tab groups can be named,
color-coded, and are always saved. You can close a group and
reopen it later.
- A tab preview is now displayed when hovering the mouse over
background tabs, making it easier to locate the desired tab
without needing to switch tabs.
- The sidebar to view tabs from other devices can now be
opened via the Tab overview menu.
Security & Privacy:
- HTTPS is replacing HTTP as the default protocol in the
address bar on non-local sites. If a site is not available
via HTTPS, Firefox will fall back to HTTP.
- Firefox now blocks third-party cookie access when Enhanced
Tracking Protection's Strict mode is enabled.
- Firefox now has a new anti-tracking feature, Bounce
Tracking Protection, which is now available in Enhanced
Tracking Protection's 'Strict' mode. This feature detects
bounce trackers based on their redirect behavior and
periodically purges their cookies and site data to block
tracking.
- Firefox now enforces certificate transparency, requiring
web servers to provide sufficient proof that their
certificates were publicly disclosed before they will be
trusted. This only affects servers using certificates issued
by a certificate authority in Mozilla's Root CA Program.
- Smartblock Embeds allows users to selectively unblock
certain social media embeds that are blocked in ETP Strict
and Private Browsing modes. Currently, support is limited to
a few embed types, with more to be added in future updates.
- Firefox now upgrades page loads to HTTPS by default and
gracefully falls back to HTTP if the secure connection fails.
This behavior is known as HTTPS-First.
- The 'Copy Without Site Tracking' menu item was renamed to
'Copy Clean Link' to help clarify expectations around what
the feature does. 'Copy Clean Link' is a list based approach
to remove - known tracking parameters from links. This option
can also now be used on plain text links.
- The Clear browsing data and cookies dialog now allows
clearing saved form info separately from browsing history.
Translations:
- Firefox now allows translating selected text portions to
different languages after a full-page translation.
- Full-Page Translations are now available within Firefox
