Commented out the following:
new_redraw_string = new_redraw_string.replace(/b.globalCompositeOperation="lighter"/gi,
'b.globalCompositeOperation="hard-light"');
Noticed that the 24eec6b version's performance was heavily dependent on the level of zoom, and as you zoomed in and decreased the amount of "light" and snakes on screen the performance improved and game was smoother for the bot.
Tested both at the same zoom levels and then experimented with zoom levels while staying on the same server.
With the above code commented out performance issues decrease and appear to be back to normal performance levels (can't compare the fps as the fps indicator also appears to have become an issue in 24eec6b)
How does your performance compare to latest stable builds of 64bit Chromium?
What are your system specs? (cpu, ram, gpu)
Other firefox extensions? Mozilla is notorious for never bothering to mitigate resource competition among extensions.
Firefox has ublock origin, privacy badger and https everywhere as other addons besides greasemonkey
I went through and tested each individual addon, and it appeared privacy badger didn't have an impact on the game either in bot or manual control.
Both https everywhere and ublock origin caused poor performance in both bot and manual mode, when tested individually.
i3-2120, 8GB, HD 5670
The hardware may be old but it can easily run the base game without any performance issues with all the above addons enabled. However even in manual mode (bot not on) there are significant performance issues.
Haven't tried chromium due to the addons clearly being an issue.
