I'v been constantly trying to switch to FF from Chrome to help Firefox market share a little bit. However there are always some issues which makes me switch back to Chrome.
Currently I'm on Firefox for over the month and I did document those things that bugs me. To be fair I should create such list for Chrome too, but I don't get that moment of frustration that often.
Here's the list for Firefox. After some items I thought it would be better to write down dates instead of sequence numbers.
Tldr: The most common issue is with unresponsive tabs which cannot be reloaded/refreshed and leads to re-typing search term / closing, reopening tab / killing firefox.
----------
1. Searching google.. loading.. it is faster to open chrome then, try to copy twice the URL (which doesn't copy/ paster), type in the search term manually and process seach results than wait them appar on firefox. Reopening tab helps on FF tho.
2. Sometimes opening a url where server is cold, I get blank page after waiting. Refresh wont help.
3. CTRL + F sometimes won't work until deleting some chars. Chrome handles this without issues.
4. Opening site in new tab - Firefox hangs. Cannot switch to other tabs, cannot close tab. End task via taskmgr helps.
5. Opening site in some tab - Firefox shows loading, loading, loading. Only closing tab, opening new one helps - site loads instantly.
6. Cannot open link in Dynamcis 365 grid.
2019-09-25: 5. repeats itself. Oh, dumb me, I was in a debugger, hitting a breakpoint.
2019-09-25: Loading, loading, loading.. reopening tab.
2019-09-25: reading text on community.dynamics.com. Suddenly, text gets distorted
2019-09-27: Viewing https://support.microsoft.com/en-us/help/3142345/microsoft-d... and opening article numbers. To go back, must press back button 3 times (history gets filled). Only 1 in chrome.
2019-10-01: Callstack in a huge javascript file? Firefox just can't cope that. It just hangs. Must wait very long
2019-10-01: Scrolling javascript file in debugger. Just empty window, no text rendered. Scrolling here and there or clicking fixes it.
2019-10-01: Javascript debugging frustrating. When I want reload page, I have continue debugger. Now it feels like firefox hangs and I have to close debug tools to refresh my page. Maybe patience could help here.
2019-10-03: Firefox slowing down my browser.. yeah, browsing huge file at https://code.msdn.microsoft.com/Sample-Quick-start-for-650db.... But it won't let me go back, won't let me refresh, i'm a victim and can't go back to my google results...
2019-10-07: Opening page.. loading... opening other page from same domain works. Refresh on first page - still loading. Close tab, open new one - works.
2019-10-07: Looks like refresh is just broken. Long running tab is loading. Loading.. loading... luckily it did load after all, well at least I thought so, because page kinda rendered. Only that it wasn't working. And then I was back to the grey "Loading" page. The issue for me here is that I can't force to reload the URL in URL bar.
2019-10-11: Opening webpage from URL. Great, site doesn't open. F5 doesn't help. Cannot switch to different tabs. Thank you for closing many windows and tabs. Closing with X doesn't work. After killing FF with task manager, you restore your session - excellent. And now no problem opening that page. Doh.
2019-10-13: Searching something via url bar... well google never opens and F5 doesn't help. And pressing ENTER doesn't help. Re-searching on new tab works.
2019-10-13: Some tab that leaks memory should be reloaded. Well waiting after CTRL+F5 and waiting and waiting... eh, closing and reopening seems to be faster.
2019-10-14: Cannot copy from from a Dynamics 365 readonly field. Which is . This actually bugs me often. Can copy on chrome.
2019-10-21: Not googling on new tab page, loading, nothing happens. New tab works.
2019-10-21: Writing github issue... scrollbar doesn't work. Well actually tab doesnt respond. Oh i'm probably opening link in new tab that loads, loads, loads... Well, killing firefox is the only way I can "unstuck". How can I love FF? :( Looking forward to write these things down for Chrome in November - maybe it happens to other browsers too? However credit to FF or GitHub - dunno - my text wasn't lost in GitHub issue input field!
2019-10-21: Search. It just doesn't search on some pages (Dynamics CRM). Chrome search works better in these cases.
2019-10-21: Cursor invisible when over Firefox. Probably OS issue, happens to Chrome too.
2019-10-21: Dropdown list doesn't work as intended. Typing chars doesn't search (jump to) matched item.
