Kind of a big update... this is the last version of Firefox for Windows 7 and Windows 8, along with macOS 10.12, 10.13, and 10.14. I know this is forcing family members to finally upgrade their (mac) OS.
More big updates:
Hardware video decoding is now enabled for Intel GPUs on Linux.
We've refreshed and streamlined the user interface for importing data in from other browsers.
The builtin editor now behaves similarly to other browsers with contenteditable and designMode when splitting a node, e.g. typing Enter to split a paragraph, and also when joining two nodes, e.g. typing Backspace at the start of a paragraph to join the paragraph and the previous one.
Pretty sure that last feature is what finally fixes the Reddit Fancy Pants editor in Firefox... exactly when Reddit is destroying itself.
IndexedDB is now also supported in private browsing without memory limits thanks to encrypted storage on disk. The temporary keys to decrypt the information are hold in RAM only and all stored information is purged at the normal end of a private browsing session from disk.
This might help WhatsApp web run in private browsing, among other sites.
The most impactful thing is definitely going to be OS compatibility... this is going to be the last version of Firefox for a long time for a lot of people.
edit: culprit found: dashlane extension for firefox causing latency and high use of resources… dashlane claims they are waiting on mozilla to review their patch submitted 3 weeks ago:
If you want to find the bug, you can run a mozregression to find what broke it (using 114 as your last known good release and 115 as your bad release).
Please reach out if you need help with this.
You can use your profile to test this pretty easily.
I genuinely think the web has become horrible enough where the browser you use does not really matter from the technical perspective.
It does, however, incredibly important to have more than 1 engine competing, as currently Firefox is the only mainstream browser not built on chromium/google.
